Is this a known limitation?

If I use the following code..:

<rich:dataTable var="price" ...>
 <f:facet name="header">
 <rich:columnGroup style="background: lightsteelblue">
 <rich:column>
 <h:outputText value="#{msgs.supplier_number}"/>
 </rich:column>
 </rich:columnGroup>
 </f:facet>
 <rich:columnGroup rendered="#{price.showSupplier}">
 <rich:column>
 <h:outputText value="#{price.leverandor.levNummer}"/>
 </rich:column>
 </rich:columnGroup>
 <rich:componentControl event="onRowContextMenu" for="contextmenu" operation="show">
 <f:param value="#{price.id}" name="rowId"/>
 </rich:componentControl>
</rich:dataTable >
<rich:contextMenu attached="false" submitMode="ajax" id="contextmenu" disableDefaultMenu="true">
....
</rich:contextMenu>

then no context menu appears (I have also tried moving the componentControl tag inside the columnGroup tag with the same result)

But if I remove the columnGroup and just displays the column values, then the context menu appear.. Is this a known problem or am I doing something wrong?
