Flex Loading external swf prevents other functions

I am able to use the Loader class to import an external swf into my project, its working great. But Im also trying to do a ImageSnapshot of the stage which works fine before the external swf is imported. After the swf is imported the ImageSnapshot no longer works.

Any idea? is there a event that the external swf is bringing wit开发者_Python百科h it that would disable it?

Try to send a LoaderContext object within the Loader.load() function. On that LoaderContext, set checkPolicyFile to true. Like this:

var loader:Loader = new Loader();
var loaderContext:LoaderContext = new LoaderContext();
loaderContext.checkPolicyFile = true;
loader.load(new URLRequest("your swf url"), loaderContext);

What the checkPolicyFile flag does is that it tells the host swf to load a policy file from the loaded swf's server. If you haven't specified that flag at loading time you will recieve a SecurityError when you try to get pixel data from the loaded swf through BitmapData.draw().
