Subject [jira] [Commented] (OPENJPA-2360) ClassCastException: DetachedValueStateManager cannot be cast to StateManagerImpl
Date Thu, 04 Jul 2013 07:14:19 GMT

    [ https://issues.apache.org/jira/browse/OPENJPA-2360?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13699813#comment-13699813
] 

Guillaume Chauvet commented on OPENJPA-2360:
--------------------------------------------

Good, I have also an @OrderColumn in my UT. If I disable this annotation, the ClassCastException
is fixed, but I loose a important feature....
In any case, the root of the problem is @OrderColumn annotation.
