Hi,
I have build a client side tree using X:tree2 tag which is working fine but
when I change it to server side tree using clientSideToggle="false"
attribute, it is giving error.
The jsp is-------
<x:tree2 value="#{treeBacker.treeData}" id="server-tree" var="
node" varNodeToggler="t" clientSideToggle="false">
<f:facet name="person">
<h:panelGroup>
<f:facet name="expand">
<h:graphicImage value="images/yellow-folder-open.png"
rendered="#{t.nodeExpanded}" border="0"/>
</f:facet>
<f:facet name="collapse">
<h:graphicImage value="images/yellow-folder-closed.png"
rendered="#{!t.nodeExpanded}" border="0"/>
</f:facet>
<h:outputText value="#{node.description}" styleClass="
nodeFolder"/>
</h:panelGroup>
</f:facet>
<f:facet name="foo-folder">
