Would someone have time to look at some classes and an XML to try to tell me why nothing is loading?

I have:

A simple interface with two combo boxes (that do load) and they are linked to two separate classes. One cb class should load an UILoader class and the other cb class initiates a TileList (linked) class. each of the 4 classes are linked to there components.
additionally I have two seperate classes to handle the XML and the URLRequest?
Thanks

my uiloader
partial code

sourceValue=theXML.key[key].swfFile;
trace("///// ui  key "+sourceValue+" //////////////////");
uiImage.source=sourceValue;

If my url is correct and it is in sourcValue which it is. Shouldn't uiImage.source=sourcValue display the file?


likewise

tilelist partial code

var imageImage:String=theXML.key[tImage].swfFile;
trace("////////////////// "+imageImage+" //////////////////");
arrayImage.push({source:imageImage});

			}
dp=new DataProvider(arrayImage);
tlImage.dataProvider=dp;

all the correct URL are in the arrayImage[] and the only thing I have left is frame one(action) in the .fla which is:

the tilelist

var cbMajorComponent:CBMajorComponent=new CBMajorComponent();

cbMajorComponent.cbMajor.setSize(200, 22);
cbMajorComponent.cbMajor.prompt = "Select a Major Key";
cbMajorComponent.cbMajor.editable=false;
cbMajorComponent.cbMajor.rowCount=15;
cbMajorComponent.cbMajor.width=110;
cbMajorComponent.cbMajor.move(0,0);
cbMajorComponent.cbMajor.x=10;
cbMajorComponent.cbMajor.y=20;

this.addChild(cbMajorComponent.cbMajor);



var cbMinorComponent:CBMinorComponent=new CBMinorComponent();

cbMinorComponent.cbMinor.setSize(200, 22);
cbMinorComponent.cbMinor.prompt = "Select a Minor Key";
cbMinorComponent.cbMinor.editable=false;
cbMinorComponent.cbMinor.rowCount=15;
cbMinorComponent.cbMinor.width=110;
cbMinorComponent.cbMinor.move(0,0);
cbMinorComponent.cbMinor.x=10;
cbMinorComponent.cbMinor.y=50;

this.addChild(cbMinorComponent.cbMinor);




var uiImageComponent:UIImageComponent=new UIImageComponent();

uiImageComponent.uiImage.setSize(50,50);
uiImageComponent.uiImage.x=135;
uiImageComponent.uiImage.y=13;
//uiImageComponent.uiImage.width=110;
//uiImageComponent.uiImage.height=50;

this.addChild(uiImageComponent.uiImage);


var tlImageComponent:TLImageComponent=new TLImageComponent();

tlImageComponent.tlImage.move(135,185);
tlImageComponent.tlImage.width=375;
tlImageComponent.tlImage.height=120;
tlImageComponent.tlImage.columnWidth=160;
tlImageComponent.tlImage.rowHeight=185;

this.addChild(tlImageComponent.tlImage);

I am having a problem with dispalying the UILoader on the mcContainer I have on my main

timeline;

I wrote a class (below) that loads fine
meaning:

sourceValue=theXML.key[key].swfFile;

this code when traced outputs all the correct URL's from the XML.

package chromatic.load_files{
	import fl.containers.UILoader;
	import flash.display.MovieClip;
	import flash.events.Event;
	import fl.data.DataProvider;
	import flash.net.URLLoader;
	import flash.net.URLRequest;
	import flash.net.*;

	public class UIImageComponent extends MovieClip {

		public var uiImage:UILoader=new UILoader();
		public var dp:DataProvider=new DataProvider();
		private var dataLoader:URLLoader=new URLLoader();
		private var theXML:XML=new XML();
		private var listURL:URLRequest=new URLRequest();

		private var arrayImage:Array=new Array();

		private var singleImage:String;
		private var key:String;
		private var fileName:String;
		private var sourceValue:String=null;
		private var evtIndex:int;
		private var evtName:String;
		private var sel:Number=-1;
		private var xmlList:XMLList;

		public function UIImageComponent():void {


		}
		public function init(fileName,key):void {
			this.fileName=fileName;
			this.key=key;
			setfileName(fileName);
			setKey(key);
			setupComponent(fileName,key);
		}
		private function setupComponent(fileName,key):void {
			this.fileName=fileName;
			this.key=key;
			uiImage=new UILoader();
			uiImage.setSize(50,50);
			uiImage.x=135;
			uiImage.y=13;
			//uiImage.width=110;
			//uiImage.height=50;
			theXML=new XML(fileName);
			theXML.ignoreWhitespace=true;
			listURL=new URLRequest(theXML);
			dataLoader=new URLLoader(listURL);
			try {
				dataLoader.load(listURL);
			} catch (error:Error) {
				trace("Unable to load requested document");
			}

			dataLoader.addEventListener(Event.COMPLETE,dataLoaded);
			//uiImage.addEventListener(Event.CHANGE, selectedName);
			//uiImage.addEventListener(Event.CHANGE,changeEvent);
			//uiImage.addEventListener(Event.COMPLETE,doTrace);
			//uiImage.addEventListener(Event.RESIZE,doTrace);
		}
		private function dataLoaded(evt:Event):void {			
			theXML=XML(dataLoader.data);
			//trace("////////////////// UI "+theXML);
			key=getKey();

			sourceValue=theXML.key[key].swfFile;
			trace("///// ui  key "+sourceValue+" //////////////////");
			uiImage.source=sourceValue;
		}
		/*
		private function selectedName():void {
		/*Combobox evt.target.setupComponent  cannot have spaces (as we have).So 

until 
		* I learn how to rid a string of spaces thus the var key
		*/


		/*this bloct to be replaced by an hotspot event
		uiImageComponent=new UIImageComponent
		
		key=concatArray[evtIndex];
		uiImageComponent.setfileName(this.fileName);
		uiImageComponent.setkey(this.key);
		uiImageComponent();
		
		}
		private function doTrace(evt:Event):void {
		trace(uiImage.width);
		uiImage.scaleContent=true;
		uiImage.maintainAspectRatio=false;
		}
		*/
		private function changeEvent(evt:Event):void {
			trace(" You selected a key");
		}
		public function setfileName(fileName):void {

			this.fileName=fileName;

		}
		public function getfileName():String {
			return fileName;
		}
		public function setKey(key):void {

			this.key=key;

		}
		public function getKey():String {
			return key;
		}
	}
}

Now when I go to the actions layer keyframe of the timeline I have:

/*
import chromatic.load_files.Main;
var main:Main=new Main();
main;
*/

var cbMajorComponent:CBMajorComponent=new CBMajorComponent();
var cbMinorComponent:CBMinorComponent=new CBMinorComponent();
var uiImageComponent:UIImageComponent=new UIImageComponent();
var tlImageComponent:TLImageComponent=new TLImageComponent();


stage.addChild(cbMajorComponent.cbMajor);
stage.addChild(cbMinorComponent.cbMinor);
mcContainer.addChild(uiImageComponent.uiImage);
mcContainer.addChild(tlImageComponent.tlImage);

Here the combobox's function fine yet they have listeners and selectedItem() traces

the above mentioned URLS but nothing appears in the mcContainer.

Could someone help me to learn how to an image to dispay here?


Thanks

Can I get some help dispaying a loaded uiloader?
Thanks
