Question

<?xml version="1.0" encoding="utf-8"?>
<mob:ScreenStackApplication xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute"
   xmlns:mob="openplug.elips.controls.*" xmlns:screen="openplug.elips.controls.screenClasses.*" creationComplete="init()">

private var myCollection:ArrayCollection = new ArrayCollection(null);
private function completeHandler(event:Event):void {
var loader:URLLoader = URLLoader(event.target);
var xml:XML = XML(loader.data);
for each (var tag:XML in xml..Country) {
var myLabel:Label = new Label();
myLabel.text=String(tag..Country_Name) + ": +" + String(tag..Country_Code);
myLabel.height=height*10/100;
myCollection.addItem(myLabel);
actReq.stop();
actReq.visible=false;
Here is something wrong
private function errorHandler(event:IOErrorEvent):void {
Alert.show(event.toString(),"Connection Error");
actReq.stop();
actReq.visible=false;
I get the alert on the alert.show .
private function init():void {
var urlLoader:URLLoader = new URLLoader();
urlLoader.load(new URLRequest("http://developer.openplug.com/twitter_app/country.xml"));
urlLoader.addEventListener(Event.COMPLETE,completeHandler);
urlLoader.addEventListener(IOErrorEvent.IO_ERROR, errorHandler);
