All,
Heres a little bit of code i knocked up to demonstrate.... For MXML -
just extend the class and tie into the functions via the override.
On another note, you might want to check if the current object
contains children - if so remove them before you remove yourself (via
the removechild)
public class UIComponentContainer extends Container
{
public var hasInit:Boolean = false;
public function UIComponentContainer():void {
init();
addEventListener(Event.ADDED_TO_STAGE, bindEvents);
addEventListener(FlexEvent.REMOVE, unbindEvents);
}
public function init():void {
// does nothing !!
}
public function redraw(_isInit:Boolean = false, _abort:Boolean =
false):void {
if ((!_isInit) && ((!hasInit) || (_abort))) return;
if (_isInit) hasInit = true;
// do something here !!
}
protected function bindEvents(_event:Event = null):void {
removeEventListener(Event.ADDED_TO_STAGE, bindEvents);
redraw(true);
}
protected function unbindEvents(_event:FlexEvent = null):void {
removeEventListener(FlexEvent.REMOVE, unbindEvents);
}
}

Ok - i did a bit of research....
you can do the following - trap for the notification
FlexEvent.Remove which occurs when a child is removed
from a container. Other than that im not sure what else to do..
Basically trap this function... my own code already did something
similar but this appears more accurate as the last
posted message......
Hope that helps some of you (by the way, the notification is raised
by the Container
object under internal::removingChild function)

Samuel

I have been using creationComplete, but there is no way for me to
remove the listeners when the object is removed from the stage, which
leads to memory leaks.
