Hello,

I try to register a PostUpdateEventListener via the hibernate.cfg.xml. Everything works fine but some values I get with the PostUpdateEvent object are at least strange.

The one thing which is most critical to my intended use is the getOldState method always returns null. I searched around and found other places where people ran into the same issue but without a hint to a solution.

This must be working somewhere - but there seems to be a certain setup where this does not work. Also JavaDoc unfortunately is quite thin in this area. Might be I just miss the right pointer?

Also the timestamp returned from PostUpdateEvent#getSession()#getTimestamp() should be 'System time before the start of the transaction' returns a strange (far to low) value, at least when I interpret it as milliseconds since 1970. This is not critical to me but it might be a hint to the issue.

I can not say much about the other fields except that the PostUpdateEvent#getState() seems to be populated as expected as the PostUpdateEvent#getPersister() returns (at least some) valid data.


I'm using Hibernate 3.2.6.GA in a IBM Websphere 6.0.2 on a 1.4.2 IBM JDK with a jta based session context backed by an Oracle 10g. The issue also occurs in the test setup where ThreadLocalSessionContext is used.

Any hint is welcome,

Kind Regards, Andreas.

I also see the same issue.. anyone got a solution for this ?

I resolved this problem by using session.merge(entity) instead of session.update(). Then getOldState() returns not null value.
