Stateful bean destruction wants extended EM to join a transaction and fails
---------------------------------------------------------------------------

                 Key: JBSEAM-426
                 URL: http://jira.jboss.com/jira/browse/JBSEAM-426
             Project: JBoss Seam
          Issue Type: Bug
          Components: Core
    Affects Versions: 1.1
            Reporter: Christian Bauer


@Name("register")
@Scope(ScopeType.CONVERSATION)

@Stateful
public class RegisterBean implements Register {

    @In
    private User currentUser;

    @In(create = true)
    private EntityManager caveatEmptorEM;

    @In(create=true)
    private transient FacesMessages facesMessages;

        if (
            verifyPasswordMismatch(currentUser.getPassword())
            ||

    @End
    public String doRegister() {
        System.out.println("################### FLUSHMODE" +
            ((HibernateEntityManager)caveatEmptorEM).getSession().getFlushMode()); // This is also wrong, different issue
        if ( usernameExists(currentUser.getUsername()) )
            return "register";

        caveatEmptorEM.persist(currentUser);
        caveatEmptorEM.flush();

        // Remove the "currentUser" from the session context. This is a detached object
        // after this method returns. We don't want it to leak into the next conversation!
        Contexts.getSessionContext().remove("currentUser");

        facesMessages
              .addFromResourceBundle("SuccessfulRegistration");
        return "login";
    }

    @Remove @Destroy
    public void destroy() {}

...
}

Exception during @Destroy:

I can't make the doRegister() method @End @Remove @Destroy, it throws exceptions.
