createCriteria returns an object deleted by previous session.delete().
When we try to update object returned by createCriteria, this update fails.
createCriteria should not return deleted objects (at least it was not in Hibernate 2)
Hibernate 3.6.8 is used.
Both session.delete() and createCriteria are in the same session and parts of the same transaction.

Is it Hibernate bug?
Any workaround for this ?
