    Problem with richfaces tree menu

    safa said Newbie

      Good Morning,
      I'm trying to create a tree menu with richfaces, but the menu wasn't shown

      My JSF code:

      <rich:tree style="width:300px"
                     value="#{parc.tree}" var="item">
                          <h:outputText value="#{item.id}" />

      My ParcList Class:

      public class ParcList extends EntityQuery {
           private static final String[] RESTRICTIONS = {};
           private Parc parc = new Parc();
           public String getEjbql() {
                return "select parc from Parc parc";
           public Integer getMaxResults() {
                return 25;
           public Parc getParc() {
                return parc;
           public List<String> getRestrictions() {
                return Arrays.asList(RESTRICTIONS);
           @In EntityManager entityManager;
           TreeNodeImpl parcTree=null;
           public void setTree(){
                List<Parc> parc = entityManager.createQuery("from Parc").getResultList();
                Iterator iter = parc.iterator();
                while (iter.hasNext()) {
                     parcTree.addChild((Parc)iter.next(), parcTree);
           public List getTree(){
                List <Parc> parcs = (List<Parc>) parcTree;
                return parcs;

      and My entity class:

      @Table(name = "parc", schema = "public")
      public class Parc implements java.io.Serializable {
           private int id;
           private AireProtegee aireProtegee;

      I use seam 2.0.3

      I really need your help,
