Quick tip: Embedded MovieClip not MovieClip?
When embedding MovieClips (with only one frame) from Flash .swf file into your Flex projects, you can fall into runtime issues:
[Embed(source="assets/preloader.swf", symbol="preloader")] public static const PRELOADER_CLASS:Class; MovieClip(new Assets.PRELOADER_CLASS());
TypeError: Error #1034: Type Coercion failed: cannot convert *** to flash.display.MovieClip.
