Hi!  
Is it true that the example code below, using weak reference listener, works and the second below don´t (myButton is a global object)? If so, why?  
[AS]  
// Example code 1 - Working  
private function setupMyButton():void  
{  
function myButtonEventHandler(event:MouseEvent):void  
{  
trace(“You clicked the button!”);  
}  
myButton.addEventListener(MouseEvent.CLICK, myButtonEventHandler, false, 0, true);  
}  
[/AS]  
[AS]  
// Example code 2 - Not working  
private function setupMyButton():void  
{  
myButton.addEventListener(MouseEvent.CLICK, myButtonEventHandler, false, 0, true);  
}

private function myButtonEventHandler(event:MouseEvent):void  
{  
trace(“You clicked the button!”);  
}  
[/AS]  
But if removing the useWeakReference param the second code example will work:  
[AS]  
// Example code 2 - Working using a normal reference  
private function setupMyButton():void  
{  
myButton.addEventListener(MouseEvent.CLICK, myButtonEventHandler);  
}

private function myButtonEventHandler(event:MouseEvent):void  
{  
trace(“You clicked the button!”);  
}  
[/AS]
