This sample works. Maybe you can see (try) what is different with your code.


  | @Stateful
  | 
  | @Scope(SESSION)
  | 
  | @Name("messageManager")
  | 
  | public class MessageManagerBean implements Serializable, MessageManager
  | 
  | {
  | 
  | 
  | 
  |    @DataModel
  | 
  |    private List<Message> messageList;
  | 
  |    
  | 
  |    @DataModelSelection
  | 
  |    @Out(required=false)
  | 
  |    private Message message;
  | 
  |    
  | 
  |    @PersistenceContext(type=EXTENDED)
  | 
  |    private EntityManager em;
  | 
  |    
  | 
  |    @Factory("messageList")
  | 
  |    public void findMessages()
  | 
  |    {
  | 
  |       messageList = em.createQuery("select msg from Message msg order by msg.datetime desc").getResultList();
  | 
  |    }
  | 
  |    
  | 
  |    public void select()
  | 
  |    {
  | 
  |       if (message!=null) message.setRead(true);
  | 
  |    }
  | 
  |    
  | 
  |    public void delete()
  | 
  |    {
  | 
  |       if (message!=null)
  | 
  |       {
  | 
  |          messageList.remove(message);
  | 
  |          em.remove(message);
  | 
  |          message=null;
  | 
  |       }
  | 
  |    }
  | 
  |    
  | 
  |    @Remove @Destroy
  | 
  |    public void destroy() {}
  | 
  | 
  | 
  | }
  |
