Read the rules before posting!
http://www.hibernate.org/ForumMailingli ... AskForHelp

Hibernate version:
3b4

I can see an exception "cannot perform lookups on timestamps"
in the case I have a composite primary key (Integer, Date)
as a result of insert (save) operation. Is it an intended behaviour?

I am having this problem also. Is it true that a timestamp can't be part of a composite key?

Any findings?

I think that is a bug on Hibernate 3.

Including a timestamp field in id/composite-id is never safe because you may never get it back again. However, you can try to use the "calendar" rahter than the "timestamp".

Please refer to the post http://forum.hibernate.org/viewtopic.php?p=2239206 to see detailed information.
