hi norman,
thank you for your quick help.
The requests happened inside a Session Scope, but (if I understand correctly)
still in different conversations. Thus I added a @(protected) annotation at the
factory method, which is called once, when the page is loaded.
I haven??t annotated any method with @(protected) However, if the Session ends, will
the Conversation end as well ? Will the persistence context be cleared as well
?
Here is the code: (the Message class and the xhtml code is like in the original
tutorial)
| @(protected)("messageManager")
| @(protected)(ScopeType.SESSION)
| @(protected)
| public class MessageManager {
|
| @(protected)
| private List<Message> messageList;
|
| @(protected)
| @(protected)(required = false)
| private Message message;
|
| @(protected)
| private EntityManager entityManager;
|
| @(protected)
| private Log logger;
|
| @(protected)
| @(protected)("messageList")
| public void findMessages() {
|
| Message m1 = new Message("T1");
| m1.setTitle("T1");
| m1.setText("text1");
| m1.setDatetime(new Date());
|
| Message m2 = new Message("T2");
| m2.setTitle("T2");
| m2.setText("text2");
| m2.setDatetime(new Date());
|
| Message m3 = new Message("T3");
| m3.setTitle("T3");
| m3.setText("text3");
| m3.setDatetime(new Date());
|
| entityManager.persist(m1);
| entityManager.persist(m2);
| entityManager.persist(m3);
|
| this.messageList = entityManager.createQuery("from Message")
.getResultList();
| logger.info("messageList initialized");
| }
|
| public void select() {
| message.setRead(true);
| }
|
| public void delete() {
| entityManager.remove(message);
|
| messageList.remove(message);
| message = null;
| }
|
| }
|

thank you,
Andreas
