    Page Action needed for Injection?

    Tobias Kilian Newbie

      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:
      <!DOCTYPE composition PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
       "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

       xmlns:h="http://java.sun.com/jsf/html"
       template="layout/template.xhtml">
      
      <ui:define name="body">
       <h1>userList</h1>
       <h:messages styleClass="message"/>
       <h:outputText value="No benutzer exists"
       rendered="#{empty benutzerList}"/>
       <h:dataTable var="benutzerIterator" value="#{benutzerList}" rendered="#{not empty benutzerList}">
       <h:column>
       <f:facet name="header">
       <h:outputText value="Id"/>
       </f:facet>
       <h:outputText value="#{benutzerIterator.id}"/>
       </h:column>
       <h:column>
       <f:facet name="header">

       </f:facet>
       <s:link view="/user.xhtml" value="#{benutzerIterator.name}" propagation="join">
       </s:link>
       </h:column>
       </h:dataTable>
      
       <div class="actionButtons">
       <s:button id="done" value="Erstelle neuen Benutzer"
       view="/user.xhtml"/>
       </div>
