Hello,
I have set following property while initializing datastore.
"hibernate.current_session_context_class", "org.hibernate.context.internal.ThreadLocalSessionContext"
And I always get session using sessionfactory.getCurrentSession() and doesn't handle session.close as I assume it's the responsibility of the framework.
But whenever I try to update the object, get following error
'org.hibernate.HibernateException: Illegal attempt to associate a collection with two open sessions'. Could you please tell me what are the possible sources of this problem?
Thanks
Chandru

Hi Chandre,
Google is your friend, apparently there are 2 sessions, in one session you read the object, in the other session you try
to update this same object.
Just setting the threadlocalsessioncontext will not close the session, except if you run in some jpa2 container
environment (which often is way to heavy). So you need to close your session yourselve. In web apps there is the nice
'open session in view' pattern, not sure what the best way in RCP's is. But maybe the open session in view pattern
provides insights for that environment to.
