ManagedPersistenceContext closed in a clustered environment
-----------------------------------------------------------

                 Key: JBSEAM-2666
                 URL: http://jira.jboss.com/jira/browse/JBSEAM-2666
             Project: JBoss Seam
          Issue Type: Bug
          Components: Core
    Affects Versions: 2.0.1.GA
            Reporter: Clint Popetz
         Attachments: mpc-passivate.diff

ManagedPersistenceContext, upon passivation, checks to see if the entity manager is dirty, and if not, closes it. I presume this is intended as an optimization. But in a clustered environment, where a snapshot of the session is taken upon each request that dirties the session, passivation will occur frequently within a conversation. In this case, the entity manager is frequently closed and recreated upon the next request, and entities in conversational beans become detached, and all sorts of bad things happen when I try to use them in the new session.

I think that to preserve the promise of long conversations, we have to keep the persistence context open across passivation, regardless of whether it's dirty. 

The attached patch removes the entityManager close().
