[jboss-user] [JBoss Seam] - @DataModel makes me go nuts or it's a bug ?

[dexjam]

Either this is a bug, or possibly i don't get it, why is this working:

--- BEGIN DOES work (TM) ---
  | @Stateful
  | @Name("admin")
  | public class AdminUserBean implements Serializable, AdminUser {
  | 
  |     @PersistenceContext()
  |     private EntityManager entityManager;
  |     
  | //    @DataModel()
  | //    private List<User> userList;
  |     
  |     @Logger Log log;
  |     
  |     /*@Factory("userList")
  |     public void fetchUserList() {
  |        userList = entityManager.createNamedQuery("User.findAll").getResultList();
  |     }*/
  |     
  |     @Factory("userList")
  |     public  List<User> getUserList() {
  |         return entityManager.createNamedQuery("User.findAll").getResultList();
  |     }
  |     
  |     @Remove
  |     public void destroy() {
  |         //No special treatment
  |     }
  |     
  | }
  | --- END DOES work (TM) ---

and this isn't???

--- BEGIN DOESn't work (TM) ---
  | @Stateful
  | @Name("admin")
  | public class AdminUserBean implements Serializable, AdminUser {
  | 
  |     @PersistenceContext()
  |     private EntityManager entityManager;
  |     
  |     @DataModel()
  |     private List<User> userList;
  |     
  |     @Logger Log log;
  |     
  |     @Factory("userList")
  |     public void fetchUserList() {
  |        userList = entityManager.createNamedQuery("User.findAll").getResultList();
  |     }
  |     
  |     /*
  |     @Factory("userList")
  |     public  List<User> getUserList() {
  |         return entityManager.createNamedQuery("User.findAll").getResultList();
  |     }
  |     */
  |     
  |     @Remove
  |     public void destroy() {
  |         //No special treatment
  |     }
  |     
  | }
  | --- END DOESn't work (TM) ---

  |         <h:dataTable value="#{userList}" var="singleUser">
  |             <h:column>
  |                 <h:outputText value="#{singleUser.id}"/>
  |             </h:column>
  |         </h:dataTable>
  |         
  |     </ui:define>
  |     
  |     </ui:composition>
  |     

Anybody, please enlighten me or point me to some very explicit documentation please.
