Question

I have an image that I am attempting to load, and then reload. Here is my code for the loading of the image:

    public function loadImage(url:String, _w:int, _h:int):void 
    {   
        this._stwidth = _w;
        this._stheight = _h;
        this._imageURL = url;

        if(!_imageURL)
        {
            return;
        }

        this.alpha = 1.0;   //need this because we might have just faded the image out

        _ldr.alpha = 0.0;
        _prog.alpha = 1.0;
        _sqr.alpha = 0.0;
        _sqr.graphics.clear();

        if(_hasLoaded) 
        {
            try
            {
                _ldr.close();
                _ldr.unload();                  
            }
            catch(e:Error)
            {
                //trace("bmdisplay has loaded once, but there was an error: " + e.message);
            }           
        }

        _ldr.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, onProgress);
        _ldr.contentLoaderInfo.addEventListener(Event.COMPLETE, onComplete);
        _ldr.contentLoaderInfo.addEventListener(IOErrorEvent.IO_ERROR, onError);
        _ldr.contentLoaderInfo.addEventListener(SecurityErrorEvent.SECURITY_ERROR, onError);
        _ldr.contentLoaderInfo.addEventListener(Event.INIT, onOpen);
        _ldr.load(new URLRequest(_imageURL));
    }

For some reason, this code will not load the image without issuing an Error upon the 2nd load.
Can someone please help me figure this out?

I am totally lost on why my variable _asLoaded would do me wrong.
I have an onComplete() handler, which sets that var to true, and I never set it to false after that.

I don’t know what else I should be trying…

Thanks

i would declare _ldr inside the function so its dead every time you start this function. and i also would not use this unload() and close() methods. its much simpler if make some thing like this (you need to have a empty movieclip called “ldrHelper”):

public function loadImage(url:String, _w:int, _h:int):void 
{
    // do your job and die bravely, no need to be global 
    var _ldr:Loader = new Loader();
    this._stwidth = _w;
    this._stheight = _h;
    this._imageURL = url;

    if(!_imageURL)
    {
        return;
    }

    this.alpha = 1.0;   //need this because we might have just faded the image out

    // now you will need to make alpha = 1 on ldrHolder since _ldr is dead after this function
    ldrHolder.alpha = 0.0;
    _prog.alpha = 1.0;
    _sqr.alpha = 0.0;
    _sqr.graphics.clear();


   // remove the old image, doesn't matter whether its empty or not
   while(ldrHolder.numChildren > 0){
         ldrHolder.removeChildAt(0);
   }

    //add image
    ldrHolder.addChild(_ldr);

    _ldr.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, onProgress);
    _ldr.contentLoaderInfo.addEventListener(Event.COMPLETE, onComplete);
    _ldr.contentLoaderInfo.addEventListener(IOErrorEvent.IO_ERROR, onError);
    _ldr.contentLoaderInfo.addEventListener(SecurityErrorEvent.SECURITY_ERROR, onError);
    _ldr.contentLoaderInfo.addEventListener(Event.INIT, onOpen);
    _ldr.load(new URLRequest(_imageURL));
}
