Dispatching events between different classes

are you losing scope in your dataLoaded function?  use trace(this) to see.

that's exactly what i did.

i have 3 classes

AS.XMLClass

AS.ControlClass

AS.DisplayClass

It's like a slideshow thing.

I have a button on stage thats connected to the control class and every time you press it

it changes the index of the image in the xmlclass and everytime that the index is changed the xmlclass needs to

dispatch and event that the index has changed and the display class is going to catch the event and change the image

everything is working except the xmlclass dispatch event or the displayclass catch event

XMLCLASS

public static const INDEX_CHANGED:String = "indexChanged";

private function dataLoaded(event:Event):void{
           
            trace("xml file is loaded");
            data = new XML(loader.data);
            dispatchEvent(new Event(XMLClass.XML_LOADED));
            totalItems = data.images.photo.length();
            setCurrentIndex(currentIndex);
}

CONTROL CLASS

import AS.XMLClass;

private var _xml = new XMLClass();

public function leftButtonClicked(){
            _xml.setCurrentIndex(_xml.currentIndex = _xml.currentIndex - 1);
        }
       
        public function rightButtonClicked(){
            _xml.setCurrentIndex(_xml.currentIndex = _xml.currentIndex + 1);
        }

DISPLAY CLASS

import AS.XMLClass;

private var _xml  = new XMLClass();

_xml.addEventListener(XMLClass.XML_LOADED, swapImage);

public function swapImage(event:Event){
            trace("working....");
        }

O yea it's a string

public static const INDEX_CHANGED:String = "indexChanged";

Still not working....

how would you change the could to make it work ?
