Loader class not firing Event.COMPLETE

[DelvarWorld]

I'm having a problem that's got me stuck in AS3. I have this seemingly simple code:

var loader:Loader = new Loader();
loader.addEventListener(Event.COMPLETE, function(event:Event):void{
    trace('hi');
});
loader.load(new URLRequest('photo.jpg')); 

The event.complete is never firing. Nothing I do works. If I make it a URLLoader and not a regular Loader it goes through fine and the event is fired, however this is an image I need to add to the stage so I need to use a Loader. But I can't figure out for the life of me why the event.complete isn't firing. I know it's loading because I can add the loader to the stage and the image shows up. Doesn't matter if I do local images or images from a server. What's going on here?

I don't know what is happening, but you should add a listener for ioerror, and try to catch SecurityErrors to find out.

Oh, figured it out. Didn't read the help files closely enough. It's

loader.contentLoaderInfo.addEventListener()

not

loader.addEventListener()

but thanks, you pointed me in the right direction
