Question about flash CS5 working with TLF TextField & self document preloader

Question

Hello everybod,
I am working on a project that document type of it is Flash CS5. I have an Document class that attached to my fla file.
in it i create a self document preloader like this :
Class Document :
package Codes
     import flash.display.Sprite;
     import flash.display.StageAlign;
     import flash.display.StageScaleMode;
     import flash.events.ProgressEvent;
     import flash.events.Event;
     public class MainDoc extends Sprite
          public function MainDoc ()
               // stage setting
               stage.showDefaultContextMenu = false;
               stage.align = StageAlign.TOP_LEFT;
               stage.scaleMode = StageScaleMode.NO_SCALE;
               // stage methods
               this.loaderInfo.addEventListener(ProgressEvent.PROGRESS, progressHandler);
               this.loaderInfo.addEventListener(Event.COMPLETE, completeHandler);
          private function progressHandler (e:ProgressEvent):void
          private function completeHandler (e:Event):void
it works true. but when i insert a TLF TextField, i get an error like this
TypeError: Error #1009: Cannot access a property or method of a null object reference.
     at Codes::MainDoc()
Please help me. i dont know what should i do & where is the problem.
I am waiting for a replay.
Thanx every body.

Hi Alan,
Thanks for the very speedy response!!
That worked, cheers.
Just for the record, if you are having a problem accessing your FlashVars (and you are using a TLFTextField in Flash CS5) and you are using external classes (i.e. you have a document class and not timeline code) you need to listen for the ADDED_TO_STAGE event before trying to access them.
For example ...
package
    import flash.display.Sprite;
    import flash.events.Event;
    import flash.display.LoaderInfo;
    public class Main extends Sprite
        public function Main():void
            if (stage) init();
            else addEventListener(Event.ADDED_TO_STAGE, init);
        private function init(evt:Event = null):void
            removeEventListener(Event.ADDED_TO_STAGE, init);
            var params:Object = loaderInfo.parameters;
            if (parent != null && parent.parent != null) {
                params = parent.parent.loaderInfo.parameters;
            // You can now loop through the params to access your FlashVars
I hope this gets fixed soon. It seems like a big oversight.

Adrian
