I want to run an Action Script 3.0 Application into a Flex Application. To do this I've done the following:

<?xml version="1.0" encoding="utf-8"?>
<mx:WindowedApplication windowComplete="loadSwfApplication()" xmlns:mx="http://www.adobe.com/2006/mxml">

    <mx:Script>
        <![CDATA[
            private function loadSwfApplication()
            {
                var urlRequest:URLRequest = new URLRequest("path/to/the/application.swf");
                swfLoader.addEventListener(Event.COMPLETE, loadComplete);
                swfLoader.load(urlRequest);
            }

            private function loadComplete(completeEvent:Event)
            {
                var swfApplication:* = completeEvent.target.content;
                swfApplication.init();  // this is a Function that I made it in the Root class of swfApplication
            }
        ]]>
    </mx:Script>

    <mx:SWFLoader id="sfwLoader"/>

</mx:WindowedApplication>

The problem is that in the calling of swfApplication.init(); the AIR Player throws me an exception:

Security sandbox violation: caller file:///path/to/the/application.swf cannot access Stage owned by app:/SWFApplicationLoader.swf.

This is because somewhere in application.swf I use the stage like this:

if (root.stage != null)
    root.stage.addEventListener(Event.REMOVED, someFunction);
root.stage.stageFocusRect = false;

How can I load this swf application and USE the stage without any problems?
