    Problems with NodeSelectedEvent

    alex sneider Newbie
      Hi everyone.

      I am using a Rich Tree component and have a problem handling the rich tree NodeSelectedEvent.

      I need to get the selected node id or name. But I get an exception handling the event:

      java.lang.ClassCastException: org.richfaces.component.html.HtmlTree cannot be cast to org.richfaces.component.html.HtmlTree

      Here is my listener:
      public class TreeListener implements NodeSelectedListener{

           public void processSelection(NodeSelectedEvent event)
                     throws AbortProcessingException {
                HtmlTree tree = (HtmlTree)event.getComponent();


      Here is my Tree class:
      public class TreeBean {

           private List<Category> categoryList;

           private TreeNode categoryTree = new TreeNodeImpl();
           private String nodeTitle;
           @Logger Log log;
           public void createTree() {
                categoryList = new CategoryList().getResultList();          
                try {
                } catch(Exception e) {
                     log.error("Error creating the category tree.", e.getMessage());
           public String getNodeTitle() {
                return nodeTitle;
           public TreeNode getCategoryTree() {
                return categoryTree;

           public void setCategoryTree(TreeNode categoryTree) {
                this.categoryTree = categoryTree;

      Here is my page:
                                                   <rich:tree value="#{treebean.categoryTree}"
                                                        var="node" icon="" iconLeaf="" nodeSelectListener="#{treelistener.processSelection}"
                                                        ajaxSubmitSelection="true" >
                                                             <h:outputText value="#{node}"/>


      I suppose it is some sort of a classpath problem. I have added the libraries to my ear content and to the manifest.

      I desperately need an answer.

      Thank you in advance.
