Problem exposing Accessor Methods on View object (ViewRowImpl.java)

Question

JDeveloper 9.03
I have a view link, ViewLinkSourceDest, that links two view objects Source and Destination. Each view object has its respective ViewRowImpl.java file created.
I have selected "Generate Accessor in View Object" in View link Properties of the View Link Wizard for both source and destination view objects.
The correct Accessor methods are available in both the source and destination ViewRowImpl files.
When I access the Source accessor method from the DestinationViewRowImpl object I receive the following error:
          ORA-00904: invalid column name
          It is also is displaying the Source view object's SQL statement with the (:1 = Destination.ID) where clause.
The error is occurring when trying to retrieve the view object using this type of method call:
          Row r = this.getSourceView();
After further investigation I have found an example set of view objects in which the error does not occur. The difference was in the ViewLink.xml file.
The ViewLink.xml file that accesses the Accessor with the error begins like this:
          <ViewLink     
               Name="ViewLink"
               Where=":1 = Destination._ID" >
The ViewLink.xml file that accesses the Accessor with no error begins like this:
          <ViewLink     
               Name="ViewLink"
               EntityAssociation ="SourceDestAssociation" >
suggesting that the use of an association would resolve this problem.
I was not able to create a View link based on an association that would generate a ViewLink.xml file that ressemble the successful file above. I could however manually add the correct entry to the xml file that caused the error and sucessfully access the Accessor method in the source object. This is not the final answer because the IDE will regenerate the ViewLink.xml file to its original state even if created with the appropriate Association.
Is this a bug?
Is the way the ViewLink.xml file created different in JDev 9.03 than in 9.02
Is there something I am missing that is causing the ViewLink.xml file to generate incorrectly?
Any suggestions would be helpful.

Steps to recreate:
1 Create SomeSuperEntityImpl.java extended by SourceEntityImpl.java and DestinationEntityImpl.java entity objects.
2 Create SourceView and DestinationView objects
3 Create SourceDestinationAssociation linking the entity object Source PK to Destination FK
4 Create SourceDestinationView linking Source and Destination view using the SourceDestinationAssociation
View the SourceDestinationView.xml file and you will see that the viewlink has Where=":1 = source.src_id"
This is the scenario that causes the initial problem with the Accessor Methods.
If the SomeSuperEntityImpl.java is removed as the super class and the same procedure is followed you will get the desired 'EntityAssociation = "package.SourceDestinationAssociation"' in the SourceDestinationView.xml file .
Hope this is a little clearer.
