Dynamic photo album

Question

Hello.
I am trying to create a dynamic photo album.
private var xmlString:URLRequest;
private var xmlLoader:URLLoader;
private var index:int;
private var pages:Array;
private function init():void {
xmlString = new URLRequest("gallery.xml");
xmlLoader = new URLLoader(xmlString);
index = 2;
pages = new Array();
xmlLoader.addEventListener(Event.COMPLETE, initData);
private function initData(event:Event):void {
var albumsXML:XML = XML(xmlLoader.data);
var entries:XMLListCollection = new
XMLListCollection(albumsXML.children());
for (var i:int = 0; i < entries.length; i++) {
var albumName:String =
entries.getItemAt(i).attribute("location");
//trace("album name: " + albumName);
var imagesEntry:XMLListCollection = new
XMLListCollection(entries.getItemAt(i).children());
for (var j:int = 0; j < imagesEntry.length; j++) {
var imageSource:String =
imagesEntry.getItemAt(j).attribute("source");
//trace("image source: " + imageSource);
addPage(albumName+imageSource, index++);
private function addPage(imageSource:String, index:int):void
var page:PortratePage = new PortratePage();
page.addEventListener(FlexEvent.CREATION_COMPLETE,
onPageCreated);
var pageAttributes:ArrayCollection = new ArrayCollection();
pageAttributes.addItem(imageSource);
pageAttributes.addItem(index);
pages[page] = pageAttributes;
trace(pages[page] + "," + pages.length);
private function onPageCreated (event:FlexEvent):void {
//do stuff
XML data is loaded just fine and the addPage function gets
called.
In it, I initialize a new page (external PortratePage.mxml),
but the handling onPageCreated function is never called.
I was told that initializing mxml instances is done
asynchronously, that's why I need to define a CREATION_COMPLETE
event but for some reason it does not work.
Anyone has any idea why?
BTW: is there a way to make external mxml objects
initialization to be synchronously?
Thanks

FlexEvent.CREATION_COMPLETE might not be dispatched unless
PortratePage is somehow a decendant of UIComponent. Or maybe you
could define your own event in PortratePage and dispatch it at the
right time.
