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(IOErrorEve nt.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.

I setup a trace and the results.
function errorCatcher(e:IOErrorEvent):void{
trace(e.currentTarget); //Object LoaderInfo
trace(e.currentTarget.loaderURL); //http:\\www.xxx.com\cat.jpg
trace(e.currentTarget.loader); // Nothing
}

Can someone verify that the trace lines are correct?

Uh how are you using trace functions? KM doesn't support this in the GUI.
I usually use a text field named debug to simulate trace

Anyway I had issues with IOError and had come across this

which might help.

Oh wait I see, the issue is more about knowing which loader failed....

I drop a simple function in my script editor.
function trace(v):void{
debug.text+=v+'\n';
}

then I call trace everytime I need to track something.

try....


function errorCatcher(e:IOErrorEvent):void{
trace(e.currentTarget); //Object LoaderInfo
trace(e.currentTarget.loaderURL); //http:\\www.xxx.com\cat.jpg
trace(e.currentTarget.loader.name);
}

cs:
e.currentTarget.loader.name does not work due to the fact the the e.currentTarget.loader does not reference anything.

Will this work ?var gell:Loader = new Loader();
addChild(gell);
gell.contentLoaderInfo.addEventListener(IOErrorEve nt.IO_ERROR, errorCatcher);

function errorCatcher(e:IOErrorEvent):void{
gell.load(new URLRequest('blank.jpg'));
}

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

Was going to use that but....
If I have multiple instances of loaders then I need to check which one did not load. I had found other references to this problem in the other forums and there solution was to use the e.currentTarget.loader to determine which one did not load.
Example of usage: An error is generated when the graphic, swf, etc could not load from the server or the reference name being loaded doesn't exist on the server.
This should work....
