[jboss-user] [JBoss Seam] - Re: Stateless Converter: First works, then ClassNotFoundExce

[bfo81]

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 at 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 at 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 ;)
