    Help!,the property 'var' of tree doesn't play role

    lee Bingquan Newbie

      The following is my tree:

      <rich:tree style="width:300px" switchType="client"
       value="#{simpleTreeBean.treeNode}" var="item" nodeFace="#{item.type}">
      
       <rich:treeNode type="common">
       <h:selectBooleanCheckbox value="#{item.selected}"/>
       <h:outputText value="#{item.title}" />
       </rich:treeNode>
      </rich:tree>

      SimpleTreeBean
      public class SimpleTreeBean {
      
       private CommonNode rootNode = null;
      
       //init tree;
       private CommonNode getTreeByStr(List list,CommonNode rootNode,String index){
       int count = 0;
       for(int i=0;i<list.size();i++){
       String str = (String)list.get(i);
       StringTokenizer toc = new StringTokenizer(str,",");
      
       String t1 = toc.nextToken();
       String t2 = toc.nextToken();
       String t3 = toc.nextToken();
       if(t1.equals(index)){
       CommonNode nodeImpl = new CommonNode();
       nodeImpl.setTitle(t3);
       rootNode.addChild(new Integer(count), nodeImpl);
       getTreeByStr(list,nodeImpl,t2);
       count++;
       }
      
      
       }
      
       return rootNode;
