We'd need to see a test case to see how you hooked up the listener

I know that natively I cannot add events to TextRange objects, so I googled and found a way of doing it. The goal is to be able to put a tooltip or show an element when somebody mouses over a certain textrange in a text field, however the event is not firing on mouseover and not sure why I have LCTextRange.as and CustomEventDispatcher.as and it inherits like this: LCTextRange -> CustomEventDispatcher->TextRange I am creating a new LCTextRange instance like so: var tr:LCTextRange = new LCTextRange(textArea, false, textArea.text.indexOf(item, prevEndIndex), textArea.text.indexOf(item, prevEndIndex)+item.length); My events are not firing and not sure why, here's what I've done. LCTextRange.as public class LCTextRange extends CustomEventDispatcher { override public function LCTextRange(owner:UIComponent, modifiesSelection:Boolean=false, beginIndex:int=-1, endIndex:int=-1) { super(owner, modifiesSelection, beginIndex, endIndex); this.addEventListener(MouseEvent.CLICK,showToolTip); //CLICK is here for testing } private function showToolTip(e:Event):void { Alert.show('over'); } } and here is the CustomEventDispatcher.as public class CustomEventDispatcher extends TextRange implements IEventDispatcher { private var eventDispatcher:EventDispatcher; public function CustomEventDispatcher(owner:UIComponent, modifiesSelection:Boolean = false, beginIndex:int = -1, endIndex:int = -1) { super(owner,modifiesSelection,beginIndex,endIndex); eventDispatcher = new EventDispatcher(this); } public function addEventListener(type:String, listener:Function, useCapture:Boolean=false, priority:int=0, useWeakReference:Boolean=false):void { eventDispatcher.addEventListener(type, listener, useCapture, priority, useWeakReference); } ....... and all the other IEventDispatcher functions.
