Expanding an af:tree node by clicking onto its label

Question

Dear all,
I am ussing af:tree same as in this link.
http://www.oracle.com/technology/products/jdev/tips/fnimphius/js_disclose_tree_path.html
But may af:tree still can't expend clicking on node label.
I am using jdeve11.1.1.2.0, here is my code.
<af:resource type="javascript" >
function expandNode(event){
var _tree = event.getSource();                   
rwKeySet = event.getAddedSet();
var firstRowKey;
for(rowKey in rwKeySet){                      
firstRowKey = rowKey;
// we are interested in the first hit, so break out here
break;
if (_tree.isPathExpanded(firstRowKey)){                        
_tree.setDisclosedRowKey(firstRowKey,false);                   
else{                       
_tree.setDisclosedRowKey(firstRowKey,true);                   
</af:resource>
<af:tree id="sTree" value="#{MenuGenerator.treeModel}" var="node"
expandAllEnabled="false" styleClass="stree" >
<f:facet name="nodeStamp">
<af:outputText value="#{node.name}" />
</f:facet>
<af:clientListener method="expandNode" type="selection"/>
</af:tree>

hi Frank,
i get it too. but behaviour is different as i thought.
lets say i click on one of the node to expand it.
then i click on it again to collapse.
but i can't do it like this because my focus is still on that node.
i mean when i click on one node to expand/collapse then i click on it again to expand/collapse.
is it possible? and how to achieve this?
