How to access a swf root from Flex 3

A while ago I had to control a swf inside flex and run into trouble. As far as I could see, you either embed or load swfs symbols, which will remove all actionscripts inside your swf, or you embed/load the complete swf with everything and keep everything intact but with toruble accessing the movieclips functions and timeline.

It also seems theat Flex 2 was able to connect to the swfs root easely, but the examples I found dindt work in Flex 3.

So, I tryed to find the root of a swf when loaded with a swfLoader and came up with this:

public static function getSwfRootFromSwfLoader(swfLoader:SWFLoader):MovieClip
{
     return ((swfLoader.content as MovieClip).getChildAt(0)
         as Loader).content as MovieClip;
}

Accessing the root of the swf after that funciton worked as a charm. I used event listeners to communicate between flex and the swf just to make sure that nothing breaks in case of a problem, but thats just my choise.

Also the functions casting in the first part might not be correct but it works since thet provably inherit from the same object.
