What is a reliable way to know when your component is displayed? The
show event is only called when a component goes from visible=false to
true. The creationComplete event is only once. My problem is I have
various views (forms basically) nested in all sorts of crazy
viewstacks and so on, and I just want them to initialize themselves
when they are shown. Problem is I can't really just drive them "from
outside" when I show them, cause they always seem null, or parts of
them are when I make them visible (usually by some viewstack change)
IE defered instantiation issues. I would like the component to throw
an event when it is displayed and clear it self out, re-fetch data,
etc, but I don't see a good event.
