Flex: weird question, can't access application property in init event of SWFLoader

Question

Very weird problem, I am new to AS, but I have to say it's hard to comprehend AS is a modern language:

      private function completed():void
      {    
       trace("completed.");    
       var player:Object = (loader.content as SystemManager).application as Object;
       player.playVideo();
       player.setSize(200,300);
      }


    SWFLoader id="loader" horizontalCenter="0" width="100%" height="362" source="http://localhost:8000/testflv1.swf" init="completed()"

What I want to do is embed a swf in another parent swf, and call a function from parent to the embedded swf. Then, I use the init event for the SWFLoader to invoke the method. Before doing this I have verified that using the same code in a button click handler, it is fine with:

var player:Object = (loader.content as SystemManager).application as Object;

But if in a init event handler, the (loader.content as SystemManager).application is a null.

Whereas, in the document of SWFLoader:

init Dispatched when the properties and methods of a loaded SWF file are accessible.

I have the same problem... it works when I test local, but when I download the flexapp(.swf) from a webserver, SystemManager isn't a SystemManager...
