UITree.getTreeNode() returns always null
----------------------------------------

                 Key: RF-3699
                 URL: http://jira.jboss.com/jira/browse/RF-3699
             Project: RichFaces
          Issue Type: Bug
    Affects Versions: 3.2.1
         Environment: Tomcat, JFS SUN RI, Facelets
            Reporter: Thomas Wabner


If have a node selection listener on my rich:tree:

<rich:tree switchType="server"
                 nodeSelectListener="#{treeMgrt.onSelect}"
                 >
                 
        <rich:recursiveTreeNodesAdaptor roots="#{treeMgrt.roots}" var="item" nodes="#{item.nodes}">

          <rich:treeNode>
            <h:outputText value="#{item}"/>
          </rich:treeNode>
          
        </rich:recursiveTreeNodesAdaptor>
      </rich:tree>  

If the onSelect(NodeSelectedEvent event) is called I do the following:
....
final UITree theTree = this.getTree(event);
final TreeNode treeNode = theTree.getTreeNode();
....

treeNode is evey time null. Also If I use the method with rowKey. I have had a look into the basic implementation and found follow code:

StackingTreeModel.java:

public TreeNode getTreeNode() {
  if (isRowAvailable()) {
     return null;
  }
  throw new IllegalStateException(
     "No tree element available or row key not set!");
}

The method isRowAvailable() returns true and the result is a null object.
