[jbossseam-issues] [JBoss JIRA] Closed: (JBSEAM-2580) JPA-Session handling and Session Beans with scope=SESSION

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.
