Subject [jira] Created: (OPENJPA-1061) Entities extending from a Mapped Superclass that defines the ID fields share the same ObjectID type parameter
Date Tue, 05 May 2009 18:28:30 GMT
Entities extending from a Mapped Superclass that defines the ID fields share the same ObjectID
type parameter
-------------------------------------------------------------------------------------------------------------

                 Key: OPENJPA-1061
                 URL: https://issues.apache.org/jira/browse/OPENJPA-1061
             Project: OpenJPA
          Issue Type: Bug
          Components: jpa
    Affects Versions: 1.2.1, 1.2.0
            Reporter: Jody Grassel
            Assignee: Jody Grassel
         Attachments: unitttest.patch

When a mapped superclass (MSC) defines @Id fields, it appears that entities extending the
MSC use the MSC's type in the generated ObjectID's type field.  This can result in unexpected
primary key collissions between entities that are not intended to be related in an entity
inheritance hierarchy.  Attached to the JIRA is a junit test case that demonstrates the problem.
