I've just converted my working Hibernate (2.1.3) application to a Hibernate - Spring application. Everything works fine until I try to update a record.
He throws the following
Exception
Code:
org.springframework.orm.hibernate.HibernateSystemException: Illegal attempt to associate a collection with two open sessions; nested exception is net.sf.hibernate.HibernateException: Illegal attempt to associate a collection with two open sessions

He tells something about 2 open session, but I can't find in the debug log where he could have opened those.
Has anyone encountered the same problem or do you know the solution to my problem? Feel free to respond ;) .
Any help would be appreciated.
