 <h:panelGrid>
 <h:panelGrid>
 <h:panelGrid>

 </h:panelGrid>
 </h:panelGrid>
 </h:panelGrid>
 </h:panelGrid>
 </f:facet>
 </rich:togglePanel>
 </h:panelGrid>
 </f:subview>

I then use this page fragment in other pages via

<jsp:directive.include file="HeaderPanelF.jspf"/>

This toggle panel works fine if it is not in an f:subview ?

But the toggleControl can not find the parent.
