Problem Using Rich Tree nodeSelectListener

[oyesiji77]

On my xhtml page i have

<rich:tree value="#{detailBean.itemTreeData}" var="item" id="selectTreeA" switchType="client" nodeSelectListener="#{detailBean.onItemSelectedA}"
 reRender="selectTreeA" selectedClass="selectedRow" ajaxSubmitSelection="true">
 <rich:treeNode id="treeNode79">
 <h:outputText value="#{item.name}" />
 </rich:treeNode>
 </rich:tree>

but anytime i click a node , There are two types of events that i receive in my listener

public void onItemSelectedA(NodeSelectedEvent event) {
UITree tree = (UITree) event.getComponent();
Object o=tree.getRowData();
}

one is the AjaxSelectedEvent and the NodeSelectedEvent, whenever i receive the NodeSelectedEvent I always get an exception whenever i attempt to invoke the getRowData()

Hi,

What exception do you see?

[oyesiji77]

java.lang.IllegalStateException: No tree element available or row key not set!

Please post bean code.
