    Outject EJB

      Hi,

      I am working on a risk managing app based on the DVD store demo in order to evaluate seam for further developments. In the searchAction.java, I have the following construct:

      @EJB @Out(scope=ScopeType.SESSION,required=false)
      AccesTicketTypeLocal accesTicketType;

      Here is its code of the bean.

      @Stateful
      @Name("accestickettypebean")
      @Scope(ScopeType.EVENT)
      public class AccesTicketTypeBean implements AccesTicketTypeLocal, Serializable {

      /** Creates a new instance of AccesTypeTickeBean */
      public AccesTicketTypeBean() {
      }


      private List ticketType;
      Map<String,TicketType> ticketTypesMap;

      @PersistenceContext
      EntityManager em;

      public void loadData(TypeFormulaire tf) {
      System.out.println("============appel de loadData ticketType avec tf="+tf.getReference());
      ticketType = em.createQuery("from TicketType c where c.typeFormulaire=:tf")
      .setHint("org.hibernate.cacheable", true)
      .setParameter("tf",tf)
      .getResultList();

      Map<String,TicketType> results = new TreeMap<String,TicketType>();

      for (TicketType tt: ticketType) {
      System.out.println("======== TicketType="+tt.getId()+","+tt.getDescription());
      results.put(tt.getDescription(),tt);
      }
      ticketTypesMap = results;
      }

      public Converter getConverter() {
      return new TicketTypeConverter(ticketType);
      }

      public Map<String, TicketType> getTicketTypes() {

      System.out.println("=======appel getTicketTypes");
      Collection tt = ticketTypesMap.keySet();
      for (String t:tt)
      {
      System.out.println(t);
      }
      System.out.println("=========fin");

      return ticketTypesMap;
      }

      public TicketType getNullTicketType() {
      return new TicketType();
      }

      static public class TicketTypeConverter
      implements Converter,
      Serializable
      {
      List tfs;

      public TicketTypeConverter(List tf) {
      this.tfs = tf;
      }

      public String getAsString(FacesContext facesContext,
      UIComponent component,
      Object obj)
      {
      if (obj == null) return null;

      String val = String.valueOf( ((TicketType)obj).getId());
      return val;
      }

      public Object getAsObject(FacesContext facesContext,
      UIComponent component,
      String str)
      throws ConverterException
      {
      if (str == null || str.length()==0) {
      return null;
      }

      String id = str;
      for (TicketType tf : tfs) {
      //System.out.println("on teste "+tf.getReference());
      if (tf.getId().equals(id)) {
      //System.out.println("on trouve "+tf.getDescription());
      return tf;
      }
      }

      return null;
      }
      }


      }


      Then I inject it via seam in a jsf page:

      <h:selectOneMenu value="#{search.ticketType}"
      converter="#{accesTicketType.converter}">
      <f:selectItems value="#{accesTicketType.ticketTypes}" />
      </h:selectOneMenu>

      <h:commandButton action="#{search.attribueTicket}"
      value="#{msgs.searchButton}"
      class="formButton" style="width: 166px;"/>


      This works great when it shows the data in the HTML list; but when I click on the button, the value search.ticketType remains at value null.

      Some help available ?

      Kind regards,
      Gerd
