cast entity to Long
When I merge entity Foo, got the following exception: trying to cast the entity to Long type, how could this be possible?
Can someone give me some help on what might be the cause? Thanks!

Which Hibernate version(SVN revision) is used by JBoss4.0.5GA? Where to get the Hibernate source code. I need to debug it.
Thanks!
