Loading local Image on IOError

programming flash

I could use some expert eyes on this. I am trying to figure out the best way to load a local image (teaseFail.png), if a web URL comes up empty.

I thought the IOError would fire the ioMarqErrorListener. But it doesn’t look that way.

So I know I’m doing it all wrong. What is the best/right way to do this?


function loadImagesForShow(webURL){
    
    preLoader.start();
             
    var urlRequest:URLRequest = new URLRequest(webURL);

    marqLoader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, onMarqProgressStatus);
    marqLoader.contentLoaderInfo.addEventListener(IOErrorEvent.IO_ERROR, ioMarqErrorListener);
    marqLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, onMarqCompleteStatus);
    marqLoader.load(urlRequest);

    loadThumbs();

}

function ioMarqErrorListener(e:IOErrorEvent):void
{
    trace("ERROR DETECTED:" + IOErrorEvent + ">>>>>>>");

    var urlRequest:URLRequest = new URLRequest("images/teaseFail.png");

    marqLoader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, onMarqProgressStatus);
    marqLoader.contentLoaderInfo.addEventListener(IOErrorEvent.IO_ERROR, ioMarqErrorListener);
    marqLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, onMarqCompleteStatus);
    marqLoader.load(urlRequest);

}
