[jboss-user] [JBoss Seam] - Re: Stateless Converter: First works, then ClassNotFoundExce
Hm... my cheers were to early. It's really funny, but the debug log goes like this:
Calling the edit page
em=org.hibernate.ejb.EntityManagerImpl@d8f5e8
Submitting the edit page plus redisplay afterwards (validation fault)
em=null
Cancelling, going back to list and editing something else
em=org.hibernate.ejb.EntityManagerImpl@3eed51
The EntityManager never stays the same. Sometimes it's null, and when not it's
always newly instantiated (see the code at the end of org.hibernate...@).
Maybe it's the right time to finally post some code ;)
