Trap a Loader error and handle it with default

[imdumb]

Hello everyone,
I am trying to trap a Loader error and handle with a default image.
There are multiple loaders so I need to catch and fill the one that errors.

var gell:Loader = new Loader();
addChild(gell);
gell.contentLoaderInfo.addEventListener(IOErrorEvent.IO_ERROR, errorCatcher);

function errorCatcher(e:IOErrorEvent):void{
 // This is not working. Have tried both lines.
 //gell = Loader(e.target.loader);
 var gell:Loader = LoaderInfo(e.target).loader;
 gell.load(new URLRequest('blank.jpg'));
 
}

gell.load(new URLRequest('cat.jpg'));

Any suggestions on this will be greatly helpful.
