Hi, I’m trying to load a external swf using the Loader object, and that part seems to be working fine. But, I can’t seem to be able to cast the LoaderInfo.content to a interface that it’s document class implements. This should be possible, shouldn’t it?

```auto

public function load()
{
    _urlRequest = new URLRequest("http://localhost/test.swf");

    _loader = new Loader();
    _loader.contentLoaderInfo.addEventListener(Event.INIT, onRequestComplete);
    _loader.load(_urlRequest, new LoaderContext(false, ApplicationDomain.currentDomain));
}

function onRequestComplete(event:Event):void
{
    var loaded:IMyInterface = IMyInterface(_loader.contentLoaderInfo.content);

    loaded.myMethod();

    addChild(_loader.contentLoaderInfo.content);
}

```
