Flex Event.ID3 dispatches twice

Why does this code

mySound.addEventListener(Event.ID3, myID3Handler);

cause t开发者_如何学编程he myID3Handler to run twice ?!

I also notice that values provided to the handler are not the same, actually the second being the correct one.

Thanks

Most probably because the mp3 file that you are loading contains ID3 info in both versions: ID3v1 and ID3v2. You can check this with winamp or other mp3 player. You can also edit the file and delete one of the ID3 versions a try to load it again to see if the handler still get's called twice.
