Subject [jira] Created: (OPENJPA-895) InternalException when querying entity that participates in both inheritance and relationships
Date Wed, 04 Feb 2009 04:41:59 GMT
InternalException when querying entity that participates in both inheritance and relationships
----------------------------------------------------------------------------------------------

                 Key: OPENJPA-895
                 URL: https://issues.apache.org/jira/browse/OPENJPA-895
             Project: OpenJPA
          Issue Type: Bug
    Affects Versions: 1.2.1
            Reporter: Dinkar Rao
         Attachments: Entity_1.java, Entity_11.java, Entity_12.java, Test.java

Can someone please take a look at this  ? This is with 1.2.x.

I have Entity_1 that is extended by Entity_11 and Entity_12. Entity_1 has a 1-m bidirectional
relationship with itself. When I query Entity_1 I get the following exception. Entities and
Test are attached.

Thanks
Dinkar
