[ http://opensource.atlassian.com/projects/hibernate/browse/HHH-1657?page=c... ] Gail Badner commented on HHH-1657: ---------------------------------- Peter, thanks for the patch. I'm using it as a starting point. It would really help if someone could provide a patch for some existing unit tests to reproduce this issue using multiple-table implementations of superclasses and subclasses. In particular, I'm looking for tests that reproduce this issue with HQL using UPDATE and DELETE. I believe that the problem using "ORDER BY" is unrelated, but if someone wants to add tests that reproduce that issue, I'd take a look at that also. The following test cases provide a good start: org.hibernate.test.joinedsubclass.JoinedSubclassTest: Table per subclass (<joined-subclass>) org.hibernate.test.join.JoinTest: Table per subclass, using a discriminator; superclass and subclasses both have join tables org.hibernate.test.mixed.MixedTest: Contains a subclass of a subclass in a separate table, using a discriminator org.hibernate.test.unionsubclass2.UnionSubclassTest: Table per concrete class -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
