Schema Changes

The following are important changes that have happened in Database Schema. You will have to issue alter table statements to your database before this version can be used. Added tables can simply be run with DBCreate

New Tables

Table Name	Class Name	Explanation	Contributor
AUDITLOG	com.jcorporate.expresso.ext.dbobj.AuditLog	Used by AuditedSecuredDBObject - an extension of SecuredDBObject that always writes an audit entry to the AuditLog table tracking who made the change, when, to what object	Mike Rimov, et al
AUDITLOG_L	com.jcorporate.expresso.ext.dbobj.AuditLogL	Provides the lookup values for the AUDITLOG table	Mike Rimov, et al
schema-changes	com.jcorporate.expresso.services.dbobj.ChangeLog	A ChangeLog object is used to record changes to other DBObjects. If logging is enabled, whenever a database change is made (add, update or delete), a ChangeLog object is written.	Michael Nash, Raul Davidovich

New Features

The following are new features added to this version:

Move password hash to UserInfo interface and its implementers: password hash no longer in User.java facade, but rather in UserInfo.java interface and its implementers. This allows more flexibility in handling external authentication.
Contributed By: Larry Hamel
Velocity support for view rendering: Velocity can now be used to render the view. See EDG for details.
Contributed By: David Lloyd
RunSQL Can Display Table Definitions: Enter the table name in the 'query' section of RunSQL and it will now display the current definition of the underlying database table. Experimental
Contributed By: Michael Rimov
RunSQL Executes Updates: RunSQL can now execute updates methods as well as select. This allows you to issue ALTER TABLE statements straight through the (secured) web interface. Experimental
Contributed By: Michael Rimov
Initial Maven integration: Currently has been tested with the site:generate target and the corresponding compile, unittest, etc reports. Not yet used for building distributions. Experimental
Contributed By: Michael Rimov
RequestRegistry automatically sets data context and security parameters: All calls to setDataContext() will no longer be necessary in client code. This info is propagated using ThreadLocal variables and the "Registry" pattern as described by Martin Fowler. Security parameters (i.e., requesting UID) are also propagated to RowSecuredDBObject, but for the sake of backwards compatibility, they are not propagated to SecuredDBObject. CheckLogin does this work. However, this functionality is also available in a servlet filter, RequestRegistryFilter. If you choose to use RequestRegistryFilter, you could do away with CheckLogin calls from the controller. We would use RequestRegistryFilter everywhere, but legacy installations have various URL paths, each of which requires filtering.
Contributed By: Michael Rimov
Customizable per-instance UserInfo: There's a new constructor in User that takes a UserInfo parameter. It allows special behavior for certain users.
Contributed By: Michael Rimov
New Method: DataObject.setFieldsWithDefaults(): Populates all null fields in the object with default values as specified by the data object's metadata. The behavior mirrors that of DefaultAutoElement.
Contributed By: Michael Rimov.
revise login bean CurrentLogin to be overridable: revise login bean CurrentLogin to be overridable, as a 'class handler' in expresso-config.xml
Contributed By: Larry Hamel
Added 'delimiter' attribute to IfMemeberOfGroup tag: If a the 'delimiter' is specified, the 'groupname' will be split on the delimiter. The user will be search for any of the named groups (a logical OR is performed).
Contributed By: Mike Traum
DataField.isChanged() works after update() and add(): Add method so that DBObject.update() and DBObject.add() can indicate when to cache the current field value as the 'original' value for purposes of isChanged() comparison. Previously, isChanged() was working for DBObject.retrieve() only.
Contributed By: Larry Hamel
AllowedHtmlPlusURLFilter: AllowedHtmlPlusURLFilter offers the recognition of a limited subset of HTML to be used within an input field. the subset has been chosen to offer some basic formatting without risking Cross site scripting (XSS) dangers.
Contributed By: Larry Hamel
Struts Validator Integration: Expresso can now use Struts Validator for validating input forms. Rules are defined in validation.xml and validator-rules.xml. See Validating user input in EDG for more details
Contributed By: Raul Davidovich
new class - com.jcorporate.expresso.core.controller.TilesController: Expresso aware implementation of the org.apache.struts.tiles.Controller interface. This allows for manipulation of the ControllerResponse for a particular tile before it is displayed, independantly of the State currently being processed. Developers should extend this class and code the execute() method.
Contributed By: Malcolm Wise
Various JoinedDataObject enhancements/fixes: You can now specify which fields to retrieve from each dataobject in the join. This list can also include expressions such as SUM(). Added custom WHERE clause facility. Aliases can be used in the custom WHERE clause and these will be translated when the WHERE clause is built. Fixed generation of ON clause when joining tables with a compound key. Provided setConnection() method to facilitate transactioning.
Contributed By: Malcolm Wise
Stored Procedure support: Now DBObjectos have built in support for database stored procedures
Contributed By: Yves Henri Amaizo

Bugs Fixed

The following are bugs fixed in this version:

Email validation int SimpleRegistration was possible to bypass: It could be bypassed if the user went to the emailValidate state of the Registration controller. Now, the emailValidate state will make sure the ValidationController was first called.
Contributed By: Mike Traum
Avoid possible NPE in JoinedDataObject: JoinedDataObject was throwing a NPE in searchAndRetrieveList when using a local connection
Contributed By: Malcolm Wise
Cactus integration bug fixes: Since struts 1.1 integration, cactus integration has not functionioned. This has been fixed.
Contributed By: Mike Traum
XMLController import now works: Import was throwing exceptions for 2 reasons: (a) XMLImportDocument.character assumed the full contents would be passes in one call and (b) virtual fields we not being skipped.
Contributed By: Mike Traum
DefaultAutoElement.parseBlocks() uses default value of a field if none provided by input.: Instead of calling it an error if there is no parameter value for a field that has a default value, DefaultAutoElement.parseBlocks() now sets the field to the default value. This is especially useful for RegisterUser, which insists on values for Industry and Employees.
Contributed By: Larry Hamel
Cron entries with any minute (-1) were not executed at the proper times: Cron entries with -1 for minute should be executed every minute which is valid for the other settings
Contributed By: Marcus Lindberg, Mike Traum
i18n fixes for SimpleLoginController: i18n some strings
Contributed By: Francesco Galli
DBConnection.getMetaData() always returned metadata from the first execution: getMetaData() now returns the metadata from the most recent query, as stated in the javadocs.
Contributed By: katya, Mike Traum
Registration approval validation entry not being set to Validated: After clicking on a registration approval link, the Validation entry was not being set to Validated. Also, an exception was being thrown in the error logs.
Contributed By: Mike Traum
Validation email will now work with SSL: If a ValidationEntry was made from the SSL port, the URL was being generated with 'http' and the SSL port, causing a failure. Now, 'https' is used if the port is the SSL port.
Contributed By: Mike Traum
Controller should give out copies of schema stack to response, not the real thing!: Controller should give out copies of schema stack to response, not the real thing! The response is per call, and shouldn't have hooks into controller's static data.
Contributed By: Larry Hamel
RegistrationDBObject.deletedUser() uses custom UID field: when deleting, check registration object map because coder MAY have used custom UidField name
Contributed By: Larry Hamel
DBConnectionPool.getWildCardsList() now returns cloned array: After reports of ConcurrentModificationException, changed method to return cloned list rather than data member.
Contributed By: Larry Hamel
Messages.getString() complains less: If given a stack of schemas in which to try to find a message bundle translation, Messages.java no longer complains unless it cannot find any translation anywhere.
Contributed By: Larry Hamel
DefaultUserInfo now uses the CacheManager, eliminating problems when changing a username: When changing a username, the old username could not be used in the registration process. The username was being cached in a Hashtable, but with no syncing for updates or deletes. This has been removed in favor of the CacheManager.
Contributed By: Mike Traum
DBObject.getValuesDefault() now uses param values in cache key: DBObject.getValuesDefault() now uses param values in cache key. Previously, the cache key was a constant '.validValues' for all param values, so that the first call set the cache, and all calls thereafter, no matter what params were used, got the same value. Now, separate calls with different params will cache separately.
Contributed By: Larry Hamel
Multipart request handler infinite loop: If a controller has a session scoped bean and a multipart parameter is submitted and an exception occurs processing the state to which the parameter is submitted, the controller dispatching gets stuck in an infinite loop. The multipart handler needs to be cleared from the session bean in all cases.
Contributed By: David Lloyd
DefaultUserInfo.add/update should test via User.getUserInfo(): centralize code for testing uniqueness of e-mail address and login name. use User.getUserInfo() so that tests are routed through proper userInfo implementation
Contributed By: Larry Hamel
Transition.getParamString() fixed to cache for controller boolean: fix param cache which ignored boolean for 'includeControllerParam'. Took effect when the same transition was used in two places in same view, with differnt controller needs (e.g., one button param, on getFullUrl() call)
Contributed By: Larry Hamel
button param for 'state' wins: make button 'state' param win out over any other 'state' param in request; this was true of 'controller' param, and now also for 'state'
Contributed By: Larry Hamel
Transition.getParameterString(boolean) now obeys boolean: fix getParameterString(boolean) which was not following promise of boolean (to include controller or not). Important for submit buttons, which may need controller param to redirect correctly in the case where form tag has different URL.
Contributed By: Larry Hamel
DBObject.deleteAll failed with customWhereClause: DBObject.deleteAll failed with customWhereClause because this clause is erased by searchAndRetrieveList(). Reset clause each time through our (memory safe) 100-at-a-time loop. Also, getCustomWhereClause already has 'WHERE' prepended, so remove this when re-appending.
Contributed By: Larry Hamel (for Marcus Lindberg)
DefaultAutoElement respects numeric field when user sets field to empty string: DefaultAutoElement respects numeric field when user sets field to empty string. it is translated into a null, and thereby preserves the isFieldNull() test which is especially important for a numeric field because getFieldInt() and similar calls will return 0 for a null field.
Contributed By: Larry Hamel
Protect against null final state: Rare null final state could occur. The isFinalState protects against it. Found trying to go to the component manager when not logged in. The SimpleLoginController trying to transition to the login screen would bail horribly. A proper transition can now occur.
Contributed By: David Lloyd
When deleting an entry in USERROLES, GROUPNEST was not checked, leading to problems with referential integrity: UserGroup will now check GroupNest before allowing deletion.
Contributed By: Mike Traum
When updating registration, SimpleRegistrationController was overwriting fields with other users' information: When a user would update a registration domain object with fields that were not set to be displayed, data from another user (the first record retrieved by the database when doing a query with no constraints) was copied into those fields.
Contributed By: Mike Traum
Removing JobQueue entry for recurring job now removes the job from the CronTab: When the JobHandler checks the JobQueue for new jobs, it will now also make sure that the JobQueue entry for current CronTab entries associated with a JobQueue entry exists. If it does not, the CronTab entry is deleted.
Contributed By: Mike Traum
Fixed DBObject Null Test Case: Null Test case was performaing a clear() and an update() with an auto-inc field. The Update() would then clear the auto-inc field, resulting in bogus test results.
Contributed By: Michael Rimov
Fixed RecordPaginator for MultiDBObject: fix multidbobject support for pagelimit, and fix pagecount.
Contributed By: Larry Hamel (for Matteo Martello)
RowSecuredDBObject now rolls back permissions created during transaction: use localconnection, if any, to create permissions. fixes bug where transactions did not roll back permissions.

Performance Enhancements

The following performance enhancements that have been coded since the last version:

Reduced Clearing of Related Caches: When non-stale values were being put in the cache system, then related caches were getting cleared, even though they didn't need to be. The new put() methods in the CacheSystem Interface allows you to drop items in the cache without clearing related caches.
Contributed By: Michael Rimov

Updates to the cache size in DBObjLimit will now instantly change the cache size: Previously, the cache size was not changed until server restart when changing Database Object Page Limits and Cache Settings (DBObjLimit). Now, it will change upon DBObjLimit.update().
Contributed By: Mike Traum
SingleDBUserInfo depreciated: SingleDBUserInfo duplicates the funcitonality of DefaultUserInfo, adding the ability to hardcode the dbconext of the database table. This is unnecessary because that functionality is available in DBOTHERMAP.
Contributed By: Mike Traum
HtmlFilter does not replace double-quote: HtmlFilter does not replace double-quote now. It is not one the list of XSS characters for typical text-field usage (see http://www.cert.org/tech_tips/malicious_code_mitigation.html#4 ), and prevents proper URL recognition in HtmlPlusURLFilter.
Contributed By: Larry Hamel

Contributed By: Larry Hamel
JoinedDataObject case insensitive queries were not checking for DataFieldMetaData.isQuotedTextType(): Amended JoinedDataObject.buildWhereClauseBuffer() to check for fields being text type when a case insensitive query is requested, as SQL function UPPER is only valid for text fields.
Contributed By: Malcolm Wise
Fixed bug where transition parameters (including the state) were sometimes (unpredictably) not being recognized: ServletControllerRequest.addButtonParams() was modifying a hashtable during enumeration, which causes unpredictable results. So, the request parameters were sometimes not loaded properly.
Contributed By: Mike Traum
fix mem leak in User.addListener scheme: fix mem leak in User.addListener scheme; the scheme is intended for class-level, 'static' listeners, but individual instances were getting added to the listener list. It tended to show up when deleting users--not a commmon action.

Quick Links

Changed APIs

The following are important changes that have happened in the framework that may require you to rewrite some of your code to fit the new API

DBObject.setSchema() called automatically; expresso message bundle searched after application's bundle: DBObject.setSchema() for each DBObject is called in ConfigManager at startup. Previously, developers had to call it within each DBObject's setup(). If they did not call setSchema(), then during resource bundle lookups for translation strings, the schema would default to the Expresso schema, so the Expresso bundle would be searched. Consequently, applications like eforum have a bunch of strings in the Expresso bundle. To accommodate this legacy expectation, MessageBundle now has the following logic: if a translation string is not found, and the current schema is not Expresso, then also search for the string in the Expresso bundle.
Contributed By: Larry Hamel
HSQL reverted to no 'cached' tables: Up through version expresso 5.1, HSQL database tables were created just like other tables. However, looking forward to HSQL updates, a special case was added to create "cached" HSQL tables sometime after expresso 5.1. (Cached HSQL tables are written to the .data file in binary format, instead of appearing as plain text in the .script file.) This 'cached' change has been reversed because 1) we have reverted to hsql 1.6.1, 2) text files are more easily viewed and manipulated 3) the cached files may have been the cause of the mysterious "already opened by another process" errors. If you already have a DB created by previous copies, you'll need to delete it and start again.

Contributed By: Mike Traum
DBException thrown on DBObject (and related) add, update, and search if field value is not valid for the data type: Data type's are now checked when doing an add, update, or search to prevent sql injection. This is implemented by setting default field masks being set according to the data type. If a match is not made, DBException will be thrown. Because of this new use of field masks, care must be taken when setting custom field masks to exclude the possibility of sql injection.
Contributed By: Mike Traum

New Features

The following are new features added to this version:

ServletControllerRequest possible instead of pure Controller Request: You can now implement a state handler as: runXXXXState(ServletControllerRequest, ControllerResponse); if you desire pure servlet usage. This avoids that nasty cast issue. Expresso will only search for the servlet controller request version if it cannot find a state handler using (ControllerRequest,ControllerResponse) parameters
Contributed By: Michael Rimov
Allow Inputs to have multiple default values: Can now set multiple default values for Inputs via setDefaultValueArray(String[]). Expresso EL options tag modified accordingly. Useful for pre-setting multiple values in a multi-select select box.

Contributed By: Malcolm Wise

Bugs Fixed

The following are bugs fixed in this version:

Fixed ControllerResponse.getString to search through schemas in the proper order: ControllerResponse.getString searches through a stack of schemas and returns the first string found. The stack was being searched in reverse order.

When using strong encryption, StringEncryption.encrypt was throwing NoSuchAlgorithmException upon class reloading: On destroy(), the encryption provider was not being removed properly from Security properly, so it would not init() properly on reload.
Contributed By: Mike Traum
fix Schema.getMembers() initialization regarding permissions of the requesting user: fix Schema.getMembers() initialization regarding permissions of the requesting user. Although SecuredDBObject assumes superuser privileges when the no-argument constructor is used, its subclass RowSecuredDBObject is less optimistic, assuming that no privileges should be given. Therefore, when Schema.getMembers() is called during schema initialization, the requesting user must be set for any such objects.

sql injection bugs in adding and updating fixed: Non-text data typed fields where open to sql injection when adding or updating. This is now fixed by setting default field masks being set according to the data type. If a match is not made, DBException will be thrown. Because of this new use of field masks, care must be taken when setting custom field masks to exclude the possibility of sql injection.
Contributed By: Mike Traum
sql injection bugs in searching fixed: When building a where clause, the fields will now be validated against field masks with default masks being set according to the data type.

Some had it defined and some did not but all were ready to use it due to inheritance from struts. I fixed the tld and tested them. The layer tags are still inconsistent and I didn't fix them because doing so would break existing code. They use the id property instead of styleId for rendering the id.

Performance Enhancements

The following performance enhancements that have been coded since the last version:

Improved FileUtils: FileUtils had a lot of 'StringTokenizer' use, when a .lastIndexOf() was just as easy to run.
Contributed By: Michael Rimov
Cached Groups for users: DefaultUserInfo.getGroups() now caches its results with a 10 minute TTL
Contributed By: Michael Rimov
Memory Reduction for MimeTypes autodetection: Switched to SoftReference for MimetypesFileTypeMap to save on memory.
Contributed By: Michael Rimov
DBObject.addToCache() DBObject.retrieveFromCache: Used pre-calculations to improve performance.
Contributed By: Michael Rimov
Memory reduction for ISOCountryCodes, ReverseDomainLookups tables: Switched to WeakReference for ISOCountry codes static data
Contributed By: Michael Rimov
Improved DBObject.deleteAll() performance: deleteAll now erases the recordset by loading each record into memory and reusing dbobjects instead of loading the entire recordset.
Contributed By: Michael Rimov
Modified Controller Security Caching: In the past, controller security was cached per user id, while controller security is gauged by group. So the isAllowed() statement has been rewritten to cache by group name instead of user id. While this may result in more cache hits required for a user, it should significantly reduce the number of cache items in memory as well as allow security settings to be shared between users with the same groups. This should result in significant performance improvements when it comes to scaling up to larger numbers of concurrent users. [And take much less memory]
Contributed By: Michael Rimov
Optimized locking in UnorderedCache: Locking scheme changed from straight synchronization to read/write locks.
Contributed By: Michael Rimov
Increase performance for Maximum size caching: Now using LRU mechanism for caches with maximum sizes. Allows you to keep the size of the cache down while still making sure the more frequently used items are still in cache.
Contributed By: Michael Rimov

Contributed By: Michael Rimov

Bugs Fixed

The following are bugs fixed in this version:

NPE in Dynamic Command: Fixed an NPE in Dynamic command if insecureDBMaint setup value was not set.
Contributed By: Micahael Rimov
DBConnectionPool Fixes: Added time to live for DBConnections so that connections that have been around for a long time get discarded and recycled.
Contributed By: Larry Hamel
Contributed By: Thierry Clement
InfiniteLoop in DBConnectionPool: Forced a specific maximum limit for looping looking for a connection before a ConnectionPoolException is thrown.
Contributed By: Michael Rimov
ArrayIndexOutOfBoundsException in DBObject.count(): There was an exception thrown if DBObject.count() was being called on a database object that had no key fields.
Contributed By: Michael Rimov
MediaDBObject Missing Constructor: Fixed a missing constructor for MediaDBObjects.
Contributed By: Michael Rimov
Read-only empty field validation in DBMaint: Fixed an error where readonly empty fields were getting flagged as errors. Of course items like that are meant for the programmer to fill in automatically before add()/update()
Contributed By: Michael Rimov

Performance Enhancements

The following performance enhancements that have been coded since the last version:

Cache TTL: Most cache items have a custom TTL as defined in the DBObjLimits/Cache Settings table. This significantly reduces memory overhead in the long term A new thread walks the cache every minute to discard non-needed items.
Contributed By: Michael Rimov

Miscellaneous Changes

The following are miscellaneous changes:

Updated EDG: Added EDG information for JoinedDataObject, MediaDBObject
Contributed By: Michael Rimov
DBMaint Dynamic Command Refactoring: Refactored a few lines of code to allow for better derivation and custom initialization in DBMaint.
Contributed By: Michael Rimov
UI improvements in ComponentManager: Component Manager will now refresh the TOC pane if needed. Now component links will automatically appear/disappear once component installation/uninstallation is complete.
Contributed By: Michael Rimov

Version: 5.1 ea-1 Released: June 17, 2003

Componentization Framework public preview. DataObject API public preview. BLOB capabilities in DBMaint. Refactoring taking place in several areas

Changed APIs

The following are important changes that have happened in the framework that may require you to rewrite some of your code to fit the new API

New ErrorCollection methods: Now the ErrorCollection has the ability to pass in parameters to your errors. This allows you to have error messages in the MessageBundle that expect parameters being passed in.
Contributed By: Kris Thompson
Refactored Login Controller into two classes: Much like how the Registration class is now into two classes so is the Login Controller There is the base class, LoginController, this contains no prompt/process methods, this is what folks should extend. Then there is the SimpleLoginController, this is the implementation example and the default login controller
Contributed By: Kris Thompson
Removed SecuredDBObject(String) constructor.: It has been deprecated for over 2 versions. It's usage also had several other problems, and it has thus been removed.
Contributed By: Michael Rimov
Removed DBObject.searchAndRetrieve(): Removed methods that have been deprecated for 2 versions. Use DBObject.searchAndRetrieveLIst() instead for much better performance.
Contributed By: Michael Rimov
core.db.TypeMapper: new TypeMapper class to use instead of Schema. All uses ot type mapping should go through that class instead.
Contributed By: Michael Rimov
Removed ConfigManager.getProperty() methods.: ConfigManager.getProperty() has been marked deprecated since Expresso version 4.0. As an ongoing cleanup effort for the code, these methods have been removed.
Contributed By: Michael Rimov
DBObject.myPool is now private: Use .getConnectionPool() instead to get at the mypool instance.
Contributed By: Michael Rimov
SecuredDBObject.get/setRequestingUid no longer throws DBException: These methods never did throw DBException, so now their method signature has been appropriately modified.
Contributed By: Michael Rimov
com.jcorporate.expresso.core.logging.LogManager is @deprecated and no longer used: core.logging.LogManager has been replaced by kernel.LogManager which provides several new features like reloadable logging configurations.
Contributed By: Michael Rimov

Schema Changes

New Tables

Table Name	Class Name	Explanation	Contributor

Modified Tables

Table Name	Class Name	Changed Field	New Definition	Explanation	Contributor
DBOBJLIMIT	com.jcorporate.expresso.services.dbobj.DBObjLimit	TTL	integer	Allows for TTL in cache systems to be set when the object is first stored. Provides memory reduction rather than ever growing cache.	Michael Rimov
ROW_PERMISSIONS	com.jcorporate.expresso.services.dbobj.RowPermissions	ROW_KEY	VARCHAR(180)	Reduced size of key for InterBase compatibility.	Larry Hamel
USERREGISTER	com.jcorporate.expresso.ext.dbobj.RegisteredUser	FirstName	VARCHAR(30)	Added LastName and FirstName fields	Sandra Cann
USERREGISTER	com.jcorporate.expresso.ext.dbobj.RegisteredUser	LastName	VARCHAR(80)	Added LastName and FirstName fields	Sandra Cann

New Features

The following are new features added to this version:

BLOB capable DBMaint: DBMaint can now handle BLOB datatypes and provide for file upload /download capabilities with enhanced capabilities for Media DBOBjecects.
Contributed By: Michael Rimov
Media DBObjects: Media DBObjects are SecuredDBObject derived classes with addBlobField() methods that also generate housekeeping fields such as file name, file size, and mime types.
Contributed By: Michael Rimov
Recognize forwards with '.xsl' extension: Recognize forwards with '.xsl' extension, and send the request to the 'xml' forward (by default, XMLViewHandler) with the xsl path as a parameter. Thus, forwards for XSL processing can be put in the configuration file in the very same way as JSP forwards.
Contributed By: Larry Hamel
new method on DBObject - public boolean hasErrors(): Allows us to check for DBObject field errors without iterating through all fields
Contributed By: Malcolm Wise
Component build process: Created a new a better way to build components like eforum into expresso without having to polute the expresso build tree.
Contributed By: Kris Thompson
Add support for ANSI joins in MultiDBObject: New methods added - setRightJoin(), setLeftJoin(), setInnerJoin() - to build the 'FROM' clause using ANSI join syntax making outer joins possible.
Contributed By: Malcolm Wise
Various DBObject enhancements: Allow case sensitive searches, added 'IN' and 'NOT IN' to denotesRange(), allow null parameter for setFieldsToRetrieve() method. This will allow a MultiDBObject to include a DBObject for join purposes only e.g. when doing a SELECT DISTINCT on a MultiDBObject and you don't want a particular DBOBjects fields in the result.
Contributed By: Malcolm Wise
Only send changed fields in DBObject through to SQL UPDATE statement: Amended DataExecutorInterface.update(), overloaded DBObject.update() and modified JDBCExecutor.update() to accept a boolean. If 'true', for each DBOBject field, added check against DataField.isChanged(). The SET clause will only include fields for which the return value is true. If no fields have changed, the UPDATE will not be done. DBOBject.update() calls JDBCExecutor.update(DataObject, boolean) with 'false' by default. The implementation of the DefaultDataField.setValue() method was changed so that it recognised when a null value was retrieved from the database to enable us to tell if the field had been changed.
Contributed By: Malcolm Wise
ExpressoLinkTransParamTag: To help Expresso work better in a cookieless environment it needed a tag to display hrefs for Transitions that have parameters associated with them. This tag was also needed because the struts link tag does not allow for nested tags which made it impossible to nest the ExpressoTransParmTag within that tag.
Contributed By: Kris Thompson
Allow option to append a custom WHERE clause in MultiDBObject: Overloaded setCustomWhereClause(String, boolean). Setting the boolean to true will cause the custom WHERE clause to be appended to that built using calls to setForeignKey() and any values in the component DBObjects.
Contributed By: Malcolm Wise
Allow ControllerResponse attributes to persist during transitions: Attributes set via ControllerResponse.setAttribute() will now be copied to the original ControllerResponse object when transitioning between states. These attributes can now also be accessed in JSP's via extended struts tags (e.g. property="@attributeValue")
Contributed By: Malcolm Wise
User.getPrimaryGroup(), implemented as user preference: User.getPrimaryGroup() is now implemented as a user preference
Contributed By: Larry Hamel
ISOValidValues and Internationalisation: Introducing a new ISOValidValue class and completion ValidValue class. ValidValue has two useful static inner classes for sorting collection of these element by value and description. ISOValidValue extends the ValidValue class and support canonisation of the description attribute using a resource bundle. In other words valid values can be internationalised programmatically.
Contributed By: Peter Pilgrim
BAT file for running Junit: Now the process of running Junit is even easier then before, simple run the bat file runJunit.bat and Junit starts up with all of the correct parameter values
Contributed By: Kris Thompson
ant task for reverse-engineering DBObjects using DBTool: A new task will create DBObject files for each Table found in a db
Contributed By: Larry Hamel
Added user listener test on regobjs: This test is intented to test the UserListener for regobjs to ensure that they get deleted when a user is deleted.
Contributed By: Kris Thompson
Refactor Registration: Pushed up the non-prompt/process methods of Registration into an abstract class and created a class called SimpleRegistration which holds all of the prompt/process classes
Contributed By: Kris Thompson
Italian Message Bundle: New Italian Translation.
Contributed By: Francesco Galli
logging convenience for controllers: add getLogger() to Controller to reduce code duplication in subclasses
Contributed By: Larry Hamel
Removed Deprecations: Several calls to deprecated methods were removed
Contributed By: Michael Rimov
New ExLink tag functionality: ExLink tag can now serve as a direct struts replacement with the same methodology as the other extension tags.
Contributed By: Malcolm Wise
New ActionMapping capabilities with Struts.: Modified `perform()' method to add ActionMapping to the ServletControllerRequest object. Also added check for an instance ServletControllerResponse so that the action forward can be retrieved from it if it indeed it was set in a controller state method.
Contributed By: Peter Pilgrim
ErrorCollection and ChainedExceptions: ErrorCollection can now add multiple errors based upon Chained Exceptions. This can allow for easier to read error reporting.
Contributed By: Michael Rimov
DBMaint DataObject capable: DBMaint is now based upon DataObjects. This means that anything implementing the DataObject interface can now be managed through DBMaint.
Contributed By: Michael Rimov
Support for GNUJAXP: SaxParserConfigurer now also looks for an installation of GNUJAXP Experimental
Contributed By: Michael Rimov
i18n at DBObject Metadata level: If passed a Locale, DBObject field names and descriptions can be localized by calling dbobject.getMetaData().getDescription(Locale l)
Contributed By: Michael Rimov
Create Cached Tables for Hypersonic: DBCreate now creates tables with the CREATE CACHED TABLE syntax if the jdbc driver is Hypersonic.
Contributed By: Michael Rimov
DBMaint Smarter with User object.: DBMaint now has a special case for User objects. If the UserInfo implementation is a DataObject, then the search icon will appear. If not, then it will not appear. Either way, although the search icon shows searching User object, it diverts to the underlying DataObject
Contributed By: Michael Rimov

Bugs Fixed

The following are bugs fixed in this version:

Fix connection pool which was returning dead connections: Although the connection pool tested whether an existing connection was dead or not, it was not discarding the dead connections, but rather returning them!
Contributed By: Larry Hamel
Input ReadOnly text boxes where being turned into hidden fields: This was a purposeful bug, meaning that someone intended for this adverse behaivor which is if you you create an Input object and define it to be READ_ONLY the InputTag would turn that into a hidden field. I fixed that so a readonly input box is created.
Contributed By: Kris Thompson
Controller Security Routing: Fix to add ControllerSecurity routing through workflow
Contributed By: Aime Bazin
Exception when Transition has null state.: Fix to prevent exception when Transition has a null state
Contributed By: Aime Bazin
'Thread not owner' error in EmailSender: Fixed Thread Not Owner error in EmailSender by calling Thread.sleep() instead of Thread.wait()
Contributed By: Larry Hamel
DBObject.delete(boolean deleteDetails) handles the deleteDetails better, transactionally if possible: DBObject.delete(boolean deleteDetails) handles the deleteDetails better: transaction is localized within a try/catch/finally, and the commit either happens or not, depending on auto-commit.
Contributed By: Larry Hamel
Email Regular Expression Fixes: Fix regexp for email to permit capital .US (for example) and not permit comma in address, for example
Contributed By: Larry Hamel
Contributed By: Mike Traum
DBTool: Fixed reverse-engineering of DBObject files--fields were not add properly
Contributed By: Larry Hamel
threading issue in DBObject with symptom 'field def not found': Fixed threading problem in DBObject by synchronizing put() to static map of object definitions in DBObject.initialize()
Contributed By: Larry Hamel
Invalid Lookup object for Audit Log: Audit log should have lookup values to AuditLogL.
Contributed By: Gene McCullough
Status Controller: Status Controller now correctly displays the Expresso to SQL to Database Type Mappings
Contributed By: Michael Rimov
Fix DBObject.delete() to use key fields, as javadoc advertises: use key fields in WHERE clause, except when object has no key fields and ALL fields are used to identify object
Contributed By: Larry Hamel
Transition.redirectTransition: url needed webapp context: add webapp context string to redirect URL; it was working before only for ROOT webapp
Contributed By: Larry Hamel
Fixed Null Values with DBMaint and Numerics/Bit Types: DBMaint was setting empty strings for DBObject numeric fields and bit types, which should be null in the underlying database.
Contributed By: Michael Rimov
DBObjcet.quoteIfNeeded fix for Bit Types: DBObjects bit type SQL wasn't getting generated properly
Contributed By: Michael Rimov
DBObject.getThisObject() wasn't copying attributes: DBObject.getThisObject() wasn't copying the requestor ID nor localconnection for transaction because of overrides by subclasses. Added "wrapper" method "newInstance()" to fix.
Contributed By: Larry Hamel
Further improved the building of components (eforum) into expresso: I recently changed the build process for eforum my making the expresso build file be the "master file" file for building but later realized that I could move the code into the eforum build file and still achive the same goal, which was to build eforum into the expresso/dist directory
Contributed By: Kris Thompson
DBObject.delete(boolean deleteDetails) transactioning: Prevent attempt to change AutoCommit if already in a transaction
Contributed By: Malcolm Wise
No Locale for error messages: There was no way to i18n error messages if you used the ErrorMessageBundleTag because if did not pass in locale info to the Message class which itself did not have the correct method for handling that. Both classes where modified.
Contributed By: Kris Thompson
Default values for SimpleRegistration in default.script: Since the Registration.java class is now abstract the security need to be moved to the SimpleRegistration.
Contributed By: Kris Thompson
Migrated the LoginController to use messages from the MessageBundle: Most of the messages used in the LoginController were hard coded to the controller, I the messages into the MessageBundle
Contributed By: Kris Thompson
changed attribue of TransitionTag called classvalue to be camel cased: The attribute of classvalue should have been classValue.
Contributed By: Kris Thompson
changed the bld-expresso-binary target and how it builds the /lib dir: This may seem minor but it leads to a greater problem I am trying to fix with getting component build files. The bld-expresso-binary target was building the WEB-INF/lib directory from pulling files from the expresso.lib directory. Since the WEB-INF directory was populated with the lib files from the expresso.lib directory in the expresso-complete-prep target it only made since to pull from that directory instead, otherwise why even create and populate that directory.
Contributed By: Kris Thompson
Fixed Bad Mapping Names: DBObject.OriginalDBName wasn't exactly a good name for it. getMappedDataContext() is the new method of getting where you've been mapped to.
Contributed By: Michael Rimov
Oracle and BatchAdds/updates: Oracle on PreparedStatement.clearParameters() throws NPEs. The errors are logged for those commands, but otherwise ignored now.
Contributed By: Marcus Lindberg
Race Condition in MessagesBundles: Fixed an unlikely to encounter Race Condition in MessagesBundles
Contributed By: Michael Rimov
Empty SchemaList and Setup: SchemaLIst ValidValues were never getting cached for an empty schema list table resulting in constant queries.
Contributed By: Michael Rimov

Performance Enhancements

The following performance enhancements that have been coded since the last version:

Delayed DBConnectionPool.getInstance: By delaying the setting. setDataConext() should not be nearly so expensive.
Contributed By: Michael Rimov
Weak References for MessagesBundles: Because MessageBundles can be rather on-again, off-again, we're using WeakReferences to all them to be GC'ed if not in use by anything.
Contributed By: Michael Rimov
DBObject.find(): If all keys are present and no special modifiers such as distinct fields then find calls retrieve() which is MUCh faster.
Contributed By: Michael Rimov

Changed Features

The following are feature changes since the last release:

Only 1 log4j config file: Expresso is now only supporting one log4j configuration file. The default one it attempts to use is %configDir%/expressoLogging.xml.
Contributed By: Michael Rimov

Miscellaneous Changes

The following are miscellaneous changes:

Improve connection pool implementation: Rework DBConnectionPool impl to remove totalPools data member, in favor of calculating this via available and inUse collections
Contributed By: Larry Hamel
Change field length in RowPermissions.java: Change max length of a primary key. Most databases have a system limit. InterBase probably has one of the lowest limits, 200 bytes for the index, which is a combination of all indexed fields, documented at http://bdn.borland.com/article/0,1410,25245,00.html
Contributed By: Larry Hamel
Expresso License added to each source file.: The Expresso Apache-style license is now at the top of every source file.
Contributed By: Tino Dai
CheckLogin.loginViaCookie() does not throw if not active user: just return false--no authentication for user whose cookie corresponds to not active, plus log warning; this allows a browser w/ cookie for NONE (who is inactive) to NOT throw exception if a regular user then tries the same browser to go to a secure page; user will just get a login prompt rather than an exception page.
Contributed By: Larry Hamel
Javadoc fix for DateTime: Incorrect parameter descriptions for the misc.DateTime utility class.
Contributed By: Rick Goeltz
Moving Strings to public or private constants: Many strings were changed to static String constants.
Contributed By: Larry Hamel

Changed APIs

The following are important changes that have happened in the framework that may require you to rewrite some of your code to fit the new API

SecuredDBObject.thisClass changed to private.: This string was originally supposed to be private, but was accidentally marked 'protected'. This consistency error was fixed in this version. It may, however, require you to add some public static final String thisClass variables to your classes to get everthing to compile.
Contributed By: Michael Rimov

New Features

The following are new features added to this version:

"Derivable MessageBundles": By using an internal stack representation to use with setSchema() for Controllers, we can now consecutively check message bundles in multiple schemas, thus allowing folks to only copy over messages they want to override from the base controllers rather than copying ALL the messages from the base controller. [Note: the base class controller must call setSchema() for its own schema for this to work properly]
Contributed By: Michael Rimov
Struts Tags and Block ControllerElement: Necessary methods have been added to help Struts Tags play well with Blocks.
Contributed By: Michael Rimov
expresso.home VM System property.: If deployed within a WAR file, you can define an expresso.home system property (usually by adding -Dexpresso.home=[whatever] to the java command line). When this is set, Expresso will use this for the %web-app% directory instead of trying to use getRealPath()
Contributed By: Michael Rimov
Registration JSP: Registration JSP has been rewritten using Struts tags and now boasts similar rendering capabilities to DBMaint. (except for read only fields)
Contributed By: Michael Rimov
Field Range Validation Checking: Support for validating field ranges so as to ensure no SQL injection attacks come through range field entries.
Contributed By: Michael Rimov
Resend Email Validation: If Registration Validation is enabled for the default registration domain, then a 'Resend Email Validation' link now appears for the login screen.
Contributed By: Michael Rimov

Bugs Fixed

<expresso:Back> tag error: Tag gave wrong URL if there was a query string in the jsp URL.
Contributed By: Michael Rimov
FastStringBuffer race condition: Race Condition if you directly used FastStringBuffer constructors.
Contributed By: Michael Rimov
JBoss Logger Compatability: Fixed LogManager initialization so that it doesn't necessarily create any console appenders if not desired.
Contributed By: Michael Rimov
NPE in Controller.unloadStateForm(): Fixed NPE in this function.
Contributed By: Michael Rimov
updateBatch() and Autoincrement fields.: Fixed exception that occured when updating batches of DBObjects with autoinc fields.
Contributed By: Michael Rimov
DBMaint and BigDecimal Fields: DBMaint wasn't displaying bigdecimal field values properly.
Contributed By: Michael Rimov
ControllerResponse Cannot Be Null: Fixed error in controller exception handler that causes this given error. Now the proper exception gets shown.
Contributed By: Michael Rimov
Weblogic Compatibility fixes: Fixed jsp pages for weblogic use.
Contributed By: Jennifer Chen
Fixed NPE in Transition.gettheUrl(true): If mapping lookup failed, then this function will now throw a proper ControllerException instead of NPE.
Contributed By: Michael Rimov
Key field size in DBMaint.search(): Numeric Key field sizes for DBMaint.search were too small.
Contributed By: Michael Rimov
Race Conditions in JobHandler: Fixed race conditions that could occur in JobHandler.
Contributed By: Michael Rimov
Fix connection pool which was returning dead connections: Although the connection pool tested whether an existing connection was dead or not, it was not discarding the dead connections, but rather returning them!
Contributed By: Larry Hamel
Security Fix: Disclosure of configuration information.: The 'Test' Servlet had a mapping enabled by default without any security system in place. It, among other things, discloses the location of the Configuration File.
Contributed By: Michael Rimov
Validation fix for web.xml: Fixed items in web.xml that SunONE Server 7 complained about during war file validation.
Contributed By: Michael Rimov
XML Parser Setting Fix: Fixed error where ConfigManager would try to set the SAXParser to use, but some app servers (such as SunONE Studio, even with 'security manager' off, won't allow it). Now Expresso will just issue a log warning when such a Security Exception happens and continue without explicitly setting the Sax Parser.
Contributed By: Michael Rimov
JobHandler not notifying upon Exception: JobHandler was not triggering a 'failure' system event if a Job threw an exception.
Contributed By: Ken Chow
Struts-Extension Tag libraries not acting consistently.: The Struts Tag libraries were not pulling up properties consistent with the properties strings given to them. This was especially true with the attribute tags.
Contributed By: Michael Rimov
Contributed By: Mike Traum
DBOtherMap: There were numerous areas in DBObject that didn't properly deal with Other Map capabilities.
Contributed By: Theirry Clement
Login.do?next: Login wasn't processing the next parameter properly.
Contributed By: Michael Rimov
Helpdesk Ticket #550: DBObject.Field Size Limitation: DBObject.setField(String fieldName, String fieldValue) inappropriately cut off char and varchar field values when there is a range prefix (e.g '<> ').
Contributed By: Katya Sadovsky
Helpdesk Ticket #553: Query support for IN modifier.: DBObject.denotesRange() needs to support the 'IN' range qualifier.
Contributed By: Katya Sadovsky
Helpdesk Ticket #552: >= and <= are not included in the 'denotes range' function.
Contributed By: Michael Rimov
Security Fix With Registration and Admin approval.: Through parameter manipulation, a malicious attacker could gain user account access privileges if the RegDomain requires Administration approval or if the Administrator has denied the registration.
Contributed By: Michael Rimov
DBMaint Search Form and Ranges: DBMaint does not attempt to restrict input field sizes to allow for field ranges to be input into the search fields.
Contributed By: Michael Rimov
HelpDesk Ticket #555/#545: Incorrect Range Quoting: DBMaint no longer attempts to blindly quote Range modifiers, but instead now validates for proper quoting.
Contributed By: Michael Rimov
HelpDesk Ticket #554: DBObject no longer truncates Field Ranges to 'field length'
Contributed By: Michael Rimov
HelpDesk Ticket #495: getRealPath() and Silverstream App Servers: Fixed getRealPath() issue by allowing for expresso.home system property instead.
Contributed By: Clinton Parham
Contributed By: Michael Rimov
NPE with iPlanet Webservers: Modified ControllerRequest.getErrorCollection() so it doesn't throw an NPE if error collection is null.
Contributed By: Lirian Ostrovica
DBMaint Update not properly displaying errors.: IF there was a database validation error while updating a DBObject, then the error was not getting properly displayed.
Contributed By: Michael Rimov
AutoDBObject Parsing and Checkboxes: If a checkbox was not properly set, then the appropriate dbobject false value wasn't getting set.
Contributed By: Michael Rimov
Default Values set in DBMaint Update: DBObject default values were getting set for missing parameters. The solution was to clear the dbobject before population.
Contributed By: Michael Rimov
getFieldBoolean() works for checkbox fields too.:
Contributed By:

Performance Enhancements

The following performance enhancements that have been coded since the last version:

Cache Optimization: If an object has zero cache size, then DBObject.addToCache() exits immediately. This saves network roundtrips in clustered environments.
Contributed By: Michael Rimov
Removed unnecessary logging initializations: Several classes used Log.getLogger() with each object instantiation. Not necessary, and this has been fixed.
Contributed By: Michael Rimov
Improved string handling in several Struts-extension tags: Switched implementation to use FastStringBuffer with pooling.
Contributed By: Michael Rimov
Switched DBObject.find() to DBObject.retrieve() when possible.: Retrieve caches, so it performs much faster than DBObject.find()
Contributed By: Michael RImov

Fixed Floating Point and Postgresql: Floating point wouldn't convert with the current casting system with Postgresql.
Contributed By: Tsanko Stefanov
DBConnectionPool.clean(): Didn't actually close and clean the proper connection.
Contributed By: Pierre A. Damas
Contributed By: Pierre Mergaux
Must_Login_First often being read from wrong schema.: In a non-'Expresso' controller, Must_Login_First was looking for messages in the app's MessagesBunde instead of the Expresso MessagesBunde. Now it first looks in the app's MessagesBundle first and if a java.lang.IllegalargumentException is thrown, it looks in the Expresso MessagesBundle instead.`
Contributed By: Michael Rimov
Block.setFormMethod: This method incorrectly checked the parameters to be 'true' or 'false' instead of 'get' or 'post'
Contributed By: Michael Rimov
Upload not releasing Streams.: Upload wasn't closing the stream for the temp file so it wasn't getting a chance to be moved until GC ran.

New Features

The following are new features added to this version:

Postpone Registration Approval: Allows the administrator to tell the system to keep the validation link for this user while the Admin waits for other issues before clicking on "accept" or "deny"
Contributed By: Michael Rimov

Bugs Fixed

The following are bugs fixed in this version:

Admin Approval Page: Fixed several issues with the Admin approval page.
Contributed By: Michael Rimov
More robust validation: Added the ability to recover from an exception by marking a URL as unvalidated thus allowing the user to come back and retry the process once the error is fixed.
Contributed By: Michael Rimov
DBObject.saveBinaryField(): Bug in binary field saving that didn't grab the DBConnection properly.
Contributed By: Karsten Voges
Log directory not being created in Linux: The Linux zip client is skipping empty directories, therefore, the build system is now copying a readme-directory.txt file into the log directory so that the linux zip programs will correctly extract the expresso binary and complete distributions.
Contributed By: Michael Rimov
ExCheckBoxTag: Currently, the expresso extended html:checkbox tag will not check if you are using values other than: yes, true, on, y. I've fixed that so that it will work with any value, as the struts tag does. (I thought I did this before, but must have neglected to post it).
Contributed By: Mike Traum
ExLinkTag: Updated ExLink tag so that it is a true struts replacement.
Contributed By: Malcolm Wise
Removed '%' signs in login email.: To help prevent any sort of wild card happening with security, percent signs are stripped from login names, during registration and login.
Contributed By: Michael Rimov

Miscellaneous Changes

Bug Fixes and Experimental Features

Quick Links

Changed APIs

The following are important changes that have happened in the framework that may require you to rewrite some of your code to fit the new API

Removed SecuredDBObject(DBConnection,String userName): Removed this mainly unused constructor because it conflicted with DBObject(DBConnection,String dataContext) constructor.
Contributed By: Michael Rimov
New DBObject Constructor DBObject(DBConnection connection, String setupTableContext);: This new constructor allows us to use transactions in dbothermap instances.
Contributed By: Michael Rimov

New Features

The following are new features added to this version:

LIMITATION_AFTER Syntax: DBConnectionPool now can support Limitation_after syntax to support HypersonicDB Experimental
Contributed By: Shash Chatterjee
New Limitation Syntax Support with MultiDBObject: New Limitation Syntax Support for MultiDBObject Experimental
Contributed By: Shash Chatterjee
RecordPaginators and MultiDBObjects: added searchAndRetrieve that works with MultiDBObjects Experimental
Contributed By: Shash Chatterjee
Transition.redirectTransition(): Similar to Transition.transition(), but it redirects the browser to the Transition's getUrl() instead of using forward(). This allows you to change the URL in the browser for situations such as CommerceCheckout where you don't want the Refresh button resubmitting a form. Experimental
Contributed By: Michael Rimov
German Translation: New german translation is now available.
Contributed By: Karsten Voges

Bugs Fixed

The following are bugs fixed in this version:

Fix deprecations; improve string constants: Fixed usages of deprecated methods; replaced many 'naked' strings with string constants
Contributed By: Larry Hamel
More Robust Email Sender: Added Retries to help deal with bad connections
Contributed By: Shash Chatterjee
NPE fix in Registration: Fixed one NPE. Fixed setting uid from the request object rather than uid as request parm.
Contributed By: Shash Chatterjee
Fixed Delete bug in JobQueue: Remove the extended "delete" method....DBObject's detail support already takes care of this.This method generated incorrect SQL if the JobQueueEntry had parms with HTML in it.
Contributed By: Shash Chatterjee
Race Condition in DBConnectionPool: Fixed Race Condition in DBConnectionPool that could cause more than MAX_CONNECTIONS to be created to the underlying database
Contributed By: Michael Rimov
Contributed By: Clinton Parham
Transaction and CLOB fields: Fixed bug where prepared statements weren't getting cleared between different uses of a DBConnection thus affecting transactions.
Contributed By: Michael Rimov
DBConnectionPool.clean() and setAvailable(): clean() was setting available to false when it was removing objects from inUse... it should be set to true instead.
Contributed By: Michael Rimov
Fixed transaction errors after update(): Update would clear the localConnection causing problems with local Connections (transactions) and DBObjects.
Contributed By: Michael Rimov
Fixed disappearing crontab entries: equals and compare() were not sufficiently differentiating between jobs in the cron queue
Contributed By: Marcus Lindberg
ControllerUtil and <logic:present>: When checking for the existence of an Output attribute, the body of the tag would execute regardless of the attribute being present.
Contributed By: Malcom Wise
Broken ControllerSecurityMatrix: ControllerSecurityMatrix was missing the initial state parameter
Contributed By: Michael Rimov
Fixed error where transactions couldn't be used with otherDBMap setups.: Added the new constructor detailed in API Changes for this version.
Contributed By: Michael Rimov
Workflow error: Fixed error for workaround with StringTokenizer bug.
Contributed By: Aime Bazin, Bazin Software Consulting
NPE Fix in Messages.java: Fixed potential NPE that would occur when the user hasn't established a Locale yet.
Contributed By: Michael Rimov
DBMaint pointer error: Fixed DBMaint taglib where it now properly looks up its own ActionMapping to build the link URL.
Contributed By: Mike Traum
Schema.requiredVersion(): Schema.requiredVersion() now functions properly as defined in the spec on the Opensource mailing list.
Contributed By: Michael Rimov
Security Problem with Registration: In the past there was no way to turn OFF self registration. Now Registration obeys all standard ControllerSecurity laws.
Contributed By: Michael Rimov
Usability Problem with Login Controller: In Expresso 5.0, if there was an Access Denied situation, the user was re-routed to the Login page, but there was no error message generated. This has now been fixed.
Contributed By: Michael Rimov
Transition.transition() not setting Title properly: When calling Transition.transition(), the ControllerResponse's title was not getting set properly.
Contributed By: Clinton Parham.
logic:iterate and nested outputs: The struts extension tag logic:iterate can now iterate Inputs, Outputs, and Transitions of nested blocks as well
Contributed By: Michael Rimov
Fixed broken Reverse Engineering Table Feature: Reverse Engineering database tables is at least now working with MySQL.
Contributed By: Donald Lobo
Fixed Exception when using setFieldsToRetrieve() and retrieve(): Fixed as reported by Malcolm Wise. You can now use setFieldsToRetrieve() with retrieve() without getting an exception now.
Contributed By: Michael Rimov
fixed src-war build: src-war now properly contains all the directory tree for building an expresso project
Contributed By: Michael Rimov
DBTool not exiting while running Hypersonic: Command line programs won't exit because Hypersonic is still running and must be shut down. Now in your command line program, execute: ConfigManager.getInstance().destroy() right before exiting and hypersonic (if it is running) will get shut down cleanly.
Contributed By: Michael Rimov
Tiles definition not validating: Fixed error where the tiles definition wasn't validating properly with latest tiles jar.
Contributed By: Michael Rimov
Users with multiple groups not validating first time.: People that should have access to controllers were not getting proper access the first time they accessed a particular controller.
