Hello,
I've set up HibernateSession for a web application via ThreadLocal as suggested here
http://www.hibernate.org/42.html
It's working but there is an exception that's popping up.
Code:
Caused by: net.sf.hibernate.HibernateException: Illegal attempt to associate a collection with two open sessions

Shall I close the session after each request or chunk of operations? Or disconnect it?
Thanks & Regards
