Hi Folks!
i have the following scenario:
I have a page with a list of users called userList.xhtml and another page where i want to
edit the previosly selected user called user.xhtml.
The users shown in userList come from the @DataModel annotated benutzerList in
BenutzerManager, which is a SFSB.
The selected user shall be injected in BenutzerManager via the @DataModelSelection
annotation.
it seems that the user is not injected and thus not outjected to user.xhtml.
So my user.xhtml shows a blank record.
Interestingly, if i add a page action into pages.xml which does nothing but call an empty
void function on the BenutzerManager, the user is correctly propagated.
Im out of ideas now.
Thanks for your help.

This is BenutzerManager.java:
|
| @Stateful
| @Scope(ScopeType.SESSION)
| @Name("benutzerManager")
| public class BenutzerManagerImpl implements Serializable, BenutzerManager {
| private static final long serialVersionUID = -6318701843857711619L;
|
| @DataModelSelection
| @Out(required = false)
| private BenutzerImpl selectedBenutzer;
|
| @Logger
| private Log log;
|
| @PersistenceContext(type = PersistenceContextType.EXTENDED)
| private EntityManager em;
|
| public void selectBenutzer()
| {
| }
|
| @DataModel
| private List<Benutzer> benutzerList;
|
| @Factory("benutzerList")
| public void findBenutzer() {
| benutzerList = em.createQuery("from BenutzerImpl benutzer")
| .getResultList();
| }
| ...
| }
|
Here is my userList.xhtml:
