But it does matter. Say I create an object on stage through code.
var result:Boolean = super.handleAdd(event);
var child:UIComponent = event.relatedObject as
UIComponent;
child.addEventListener(MouseEvent.CLICK,
handleChildClick,
false, 0, true);
then later I delete all the child objects there will be a reference
from the addEventListener floating around so child won't be removed
from memory.
When you say a to b what do you mean?
