Is this a bug or is this expected? What I want to do is have a button in the header of the collapsible panel that will allow me to close the collapsible panel, when the collapsible panel is expanded or not expanded. For example, I have the following Facelets code:

[code]<ice:panelCollapsible expanded="#{entry.expandPanel}" rendered="#{entry.display}">
<f:facet name="header">
<ice:panelGroup>
<ice:panelGrid columns="2">
<ice:outputText value="Column" />
<ice:commandButton type="submit" value="X" action="#{manager.closePanelCollapsible}" />
</ice:panelGrid>
</ice:panelGroup>
....
[/code]

If I click on the button when the collapsible panel is not expanded, nothing happens - i.e. the closePanelCollapsible method is not invoked. However, if I click on the button when the collapsible panel is expanded, the action method closePanelCollapsible gets called!
