Access properties of loaded SWF file in Flex

I had a requirement of loading a Flash CS3 SWF file into my Flex application and access its properties. I tried to follow the recommended way using the SystemManager class by Adobe.

This did not work for me. The file loaded but when I tried to access the properties of the loaded SWF, it always gave me an error.

I discussed this with my colleague, Sumant Mishra. He gave me a simple hack which actually worked like charm. Check out the code below:

private function onSWFInit(e:Event):void
{
	var fl:FlexLoader = e.target.getChildAt(0) as FlexLoader;
	var loadedSWF:* = fl.getChildAt(0);
	loadedSWF.init(); //init() funciton is on the main timeline of loaded SWF
}
<mx:SWFLoader id="previewLoader"
                complete="onSWFInit(event)"/>
