Set a panelMenuGroup as expanded inside a dataTable

[fleabite]

Hi there,
for example I have something like the following code:

<h:form>
<rich:dataTable value="table">
<rich:column>
<rich:panelMenu>
<rich:panelMenuGroup expanded="true" label="Group">
<rich:panelMenuItem label="Item"></rich:panelMenuItem>
</rich:panelMenuGroup>
</rich:panelMenu>
</rich:column>
</rich:dataTable>
</h:form>

I set the panelGroup as expanded but it's not working. Can somebody help me please? (I was trying it with RichFaces 3.2.0, 3.2.2 and 3.3.0_Beta
