Hi all,

sometimes I find useful to be able to do some initialization once my
component is attached to its hierarchy, mainly to be able to call
getPage(). For example, if there are relevant events along some page
lifecycle maybe panels contained in it may want to add themselves as
listeners: ((MyPage)getPage()).addMyEventListener(this).

Or maybe a model is attached to the page and you don't want to pass it
deep down the hierarchy but just obtain it from the page when needed.

For now I'm just visiting page components first time the page is
attached (that is, I'm overriding onAttach).

This implementation is fine but maybe the aforementioned event should
be a provided, standard one. What do you think about it?

Thank you in advance
Cheers,
Carlos
