JPA-Session handling and Session Beans with scope=SESSION
---------------------------------------------------------

                 Key: JBSEAM-2580
                 URL: http://jira.jboss.com/jira/browse/JBSEAM-2580
             Project: JBoss Seam
          Issue Type: Bug
          Components: Core
    Affects Versions: 2.0.1.GA
         Environment: MacOS X 10.5, Java 5 (Apple), Glassfish v2u1
            Reporter: Cyrill Rￃﾼttimann
            Priority: Blocker


I have two session beans with scope=SESSION, the CustomerManager and the SportEquipmentManager. While accessing the sport equipments of a customer, I get a org.hibernate.LazyInitializationException at the method allSportEquipments():

org.hibernate.LazyInitializationException: failed to lazily initialize a collection of role: yy.ddd.ttt.customer.domain.Customer.sportEquipments, no session or session was closed

@In(value = SeamConstants.NAME_ENTITYMANAGER)
    private EntityManager mEntityManager;

    @DataModel(value = "sportequipments")
    private Set<SportEquipment> mSportEquipments;

    @In(value = "customerManager", create = true)
    private CustomerManager mCustomerManager;


    private SportEquipmentType mCurrentSportEquipmentType;

    @Factory("sportequipments")
    public void allSportEquipments() throws PersistencyException {
        final Customer customer = mCustomerManager.getCustomer();
        mSportEquipments = customer.getSportEquipments();
    }

The interesting thing is that this happens only, if I am accessing the SportEquipmentManager after using the CustomerManager. If I am acessing the SportEquipmentManager directly, I am not hit with the exception. Using the CustomerManger means, opening a page with access to the CustomerManager's method.
