You want to add the listener to the thing that dispatches the event, the
application, and declare the handler in the component.
Application.application.addEventListener("buttonLabelEvent",
buttonLabelHandler);
You will need to import the custom event.

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("buttonLabelEvent",
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..
