You'd be better listening to some property in your model and update that
property when tabs are changing. Your approach doesn't convince me.
But then, maybe I didn't get it right...

Subject: Re: [flexcoders] child component listens for event on parent
I was able to get the event happening by changing the component code to be:
private function postInit():void {
Application. application. addEventListener ("buttonLabelEve nt",
buttonLabelHandler) ;
}
but now the event seems to trigger 3 times for every tab change but doesnt
trigger on the first tab change...
And the app takes forever to compile as well...
Something still not right..
Please help..
