Flex: How to access movieclips within an imported swf

Answer 1

Was test.swf created with an earlier AS version? According to this swfs published for AS 1.0/2.0 runs in a different AS virtual machine than AS 3.

The parent AVM2 SWF file will not have access to the properties, methods, or objects of the loaded AVM1Movie object.

Answer 2

You can access them directly, using their instance names.

private function swfLoaded():void {
    var clip1:MovieClip = MovieClip(loader.content.myClip1);
    var clip2:MovieClip = MovieClip(loader.content.myClip2);
    // ...
}
