hello all,
I'm habig a problem with the session.update() operation.
I'm using hibernate 3.0.4 and Oracle 9x.
I have a regular flow of getting an object using a session.createQuery(), updating his values (including some many-to-many relations) and then transaction.commit(). I dicovered that this set of operation doesn't changes anything in the DB so i'v tried to add a session.update() before the transaction.commit() for existing objects and a session.save() for a new object. the problem is i get the following exception:
Code:
org.hibernate.HibernateException: Illegal attempt to associate a collection with two open sessions
