Because the "action" event was not caught by it's immediate container
(the Layout component), it propagated up with a new origin: the Layout
component itself. so onActionFromLayout() would work (because the id
'layout' will have been autoassigned by Tapestry).
The concept here is that the Layout component should limit how much of
its internal structure is exposed to the outside world: it should
ideally be a black box.
Often, a component will capture "action" events from one or more
components and trigger new events with names customized to what the
component does; here is might trigger an "edit" event, and you would
name your method onEditFromLayout().
