Manipulate movieclip from custom class

Question

Hello.
I have a movieclip (instance name preload), inside of it, I have another movieclip (bar) ... what i'm trying to do is a preloader for external files... i have a custom class and i what to manipulate my movieclip preload from it... you know verify the progress of the load:
Inside my class a have this function
public function loadProgress(e:ProgressEvent):void {
            percent=e.bytesLoaded/e.bytesTotal*100;
            rutaDos.preload.bar.scaleX=percent;
rutaDos is a reference to the stage... it works, I'm sure of it... the problem is:rutaDos.preload.bar.scaleX; I upload the files but it doesn't verify the progress of the load.
thanks for the help

the complete class is:
package com.ludwing{
    import flash.net.*;
    import flash.events.*;
    import flash.display.*;
    import fl.transitions.*;
    import fl.transitions.easing.*;
    import flash.display.Stage;
    import gs.TweenMax;
    import gs.easing.*;
    import gs.events.*;
    public class Transiciones extends MovieClip {
        public var url:URLRequest;
        public var loader:URLLoader;
        public var rutaDos:MovieClip;
        public var imgLoader:Loader;
        public var movie:MovieClip;
        public var container:Sprite;
        public var bg:Boolean;
        public var porcentaje:Number;
        public function Transiciones(mRuta:MovieClip, miRuta:String,isBG:Boolean,contain:MovieClip) {
            rutaDos=mRuta;
            bg=isBG;
            movie=contain;
            container=new Sprite();
            url=new URLRequest(miRuta);
            imgLoader=new Loader();
            imgLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, onLoaderComplete);
            imgLoader.load(url);
        public function onLoaderComplete(e:Event) {
            imgLoader=new Loader();
            imgLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, imgComplete);
            imgLoader.contentLoaderInfo.addEventListener(Event.INIT, imgInit);
            imgLoader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, loadProgress);
            imgLoader.load(url);
        public function loadProgress(e:ProgressEvent):void {
            porcentaje=e.bytesLoaded/e.bytesTotal*100;
            rutaDos.preload.bar.rotation=90;
        public function imgInit(e:Event) {
            movie.alpha=0;
            rutaDos.preload.alpha=1;
        public function imgComplete(event:Event) {
            rutaDos.preload.alpha=0;
            movie.addChild(imgLoader);
            var myTween:TweenMax = TweenMax.to(movie, 1, {alpha:1, ease:Circ.easeOut});
            myTween.addEventListener(Event.COMPLETE, onTransitionFinish);
        public function onTransitionFinish(e:Event):void {
            //MovieClip(root).gotoAndPlay(2);
            //rutaDos.ext.gotoAndStop(2)
            /*var my_parent:MovieClip=parent.parent as MovieClip;
            my_parent.nextSection=2;
            my_parent.gotoAndStop(my_parent.nextSection);*/
            //rutaDos.stage.addEventListener(Event.RESIZE, resizeHandler);
            if (bg==true) {
                rutaDos.gotoAndStop(14);
I try to use an empty movieclip to load a external swf (instance name: ext) this way:
var transicion:Transiciones=new Transiciones(this, "welcome.swf",true,ext);
The external swf loads correctly, but when it is loading (i mean de progress load), the preload doesn't work....
