well - show event doesn't appear to fire unless I manually twiddle with
.visible
Using the parents change event means I can't just add my component to a
plain old canvas as Canvas doesn't fire change..
So my component needs to know more about how its being used then really
seems proper for a reusable component ?
Am I missing something here? Surely other people have run across the same
situation ? Mostly I just want my component to reset its
tab navigator to the first tab each time its shown (I do other stuff too).
It really can't be this unusual can it ?

Hi Matt,
Hmm - that might work, if I use the .parent field to find the components
parent I could avoid hard coding parent names,etc...
But it feels like it violates encapsulation - the component really
shouldn't need to 'poke' its parent just
to find out when its being used/viewed.
I'll also experiment more with show/hide - maybe I missed something in
the docs...
Thanks!
