Problem with empty x:tree

Hi, 

I do not know if I´m misunderstanding something, but anyone can tell me how 
to create an empty x:tree component?

When I try to update my tree and the root element does not have any children 
in the new tree, i receive an IndexOutOfBoundException and if I try to set 
the treeModel to null the component try to render and obviously I get an 
error on the first field.

Here is my JSP code :

<x:tree id="tree" value="#{DesktopBean.treeModel}" 
var="treeItem"
styleClass="standardTreeTable"
headerClass="standardTreeTable_Header"
rowClasses="standardTable_Row1,standardTable_Row2"
columnClasses="standardTable_ColumnCentered, standardTable_ColumnCentered, 
standardTable_ColumnCentered, standardTable_ColumnCentered"
selectedNodeClass="treenodeSelected"
nodeClass="treenode"
expandRoot="true" >
<x:treeColumn>
<f:facet name="header">
<h:outputText value="Label" />
</f:facet>
<h:outputText value="#{treeItem.labelTagDesktop}" />
</x:treeColumn>
<h:column>
<f:facet name="header">
<h:outputText value="ID" />
</f:facet>
<h:outputText value="#{treeItem.idDesktop}" />
</h:column>
<h:column>
<f:facet name="header">
<h:outputText value="Nome Tag" />
</f:facet>
<h:outputText value="#{treeItem.nomeTagDesktop}" />
</h:column>
</x:tree>

Thanks
Rogerio

Suggestion: Most people are using <t:tree2> now.  You will probably
find more people able to help you with that one.
