Method Detail

retrieveCachedValueInForm

protected void retrieveCachedValueInForm(ControllerResponse response,
                                         String oneFieldName,
                                         Input i)
                                  throws ControllerException

Used to set values in created db objects to the values found (if any) in the form cache. (the form cache is what people type into an HTML form, and if there is an error, we cache those values in order to send back the form (with error message) and have their typing preserved for the next try.)

we override this method to have dbobjects get the value form cache.

Overrides:

retrieveCachedValueInForm in class DefaultAutoElement

Parameters:

i - the Input to retrieve from.

oneFieldName - the dataobject field name

response - the ControllerResponse.

Throws:

ControllerException
