Access function from a loaded external SWF

Question

So I have 2 swfs, one is mainly used to loading the other.
The problem I have is that I'd like to use a "onClickPause" function from the embeded swf after pressing a button.
Unfortunately I'm getting this error:
ReferenceError: Error #1069: Property onClickButtonPause not found on dk.game.main.Main and there is no default value.
Which is understandable since the function is located in: dk.game.view.AppView
Here's the code:
var loader: Loader = new Loader();
loader.contentLoaderInfo.addEventListener(Event.COMPLETE, onLoadComplete);
loader.load(new URLRequest('myApp.swf'));
function onLoadComplete(e: Event): void {
    var loaderInfo: LoaderInfo = e.target as LoaderInfo;
    addChild(e.target.content);
    var swf: Object = loaderInfo.content;
    button_2.addEventListener(MouseEvent.CLICK, fl_Click);
    function fl_Click(event: MouseEvent): void {
        swf.onClickPause();
Now how do I go about it from here?

Answer 1

Your best bet is to make the swf you are loading implement an Interface. The reason I recommend doing this is you can then cast your loaderInfo.content to that Interface and be sure the method is available. The reason I did not suggest just casting to the Document Class itself is if you do, the entire Document Class definition will get compiled into the loading swf, which presumably is part of what you're trying to avoid by loading it separately.
The code would then look something like this:
function onLoadComplete(e: Event): void {
    var loaderInfo: LoaderInfo = e.target as LoaderInfo;
    addChild(e.target.content);
    var swf:IYourInterface = loaderInfo.content as IYourInteface;
    if (swf) {
         button_2.addEventListener(MouseEvent.CLICK, fl_Click);
         function fl_Click(event: MouseEvent): void {
             swf.onClickPause();
     } else {
          trace('loaded MC does not implement IYourInterface');
