The confusion is probably caused by the fact that a UICommand
component needs to have a rendered attribute that is page-scoped
rather than request-scoped.
The rendered attribute value needs to remain constant from the first
request's RenderResponse phase until the next request's
InvokeApplication phase.
This is because each phase checks to insure that a component is
rendered=true before executing for a particular component.
If the rendered value is only true during the first request (for
generating html representation), then during the second request, the
component will not "exist" to generate action events.
