Load SWF inside naviteWindow [AIR]

Hello,

I have an AIR application where I have to load a SWF from a server.

At some point the user will click on a button and that button will create a new nativeWindow.

Inside that nativeWindow we have a stage reference.

I just want to load a SWF, addChild it to the stage and be happy!  😛

But I'm getting this error:

SecurityError: Error #2070: Security sandbox violation: caller http://somewhere.com/swfapp.swf cannot access Stage owned by app:/Teste.swf.
at flash.display::Stage/get stageWidth()
at com.swfapp::MainClass/initApp()
at flash.display::DisplayObjectContainer/addChild()
at flash.display::Stage/addChild()
at NativeWindowSWFLoader/loadSWFURLComplete()

I'm using a normal Loader:

private function loadSWFFromURL():void
{
          var context:LoaderContext = new LoaderContext();
          context.applicationDomain = ApplicationDomain.currentDomain;
          context.securityDomain = SecurityDomain.currentDomain;
          context.allowLoadBytesCodeExecution = true;
          context.allowCodeImport = true;
          loaderSWFURL = new Loader();
          loaderSWFURL.contentLoaderInfo.addEventListener(Event.COMPLETE, loadSWFURLComplete);
          loaderSWFURL.load(new URLRequest(urlSWF));
}

private function loadSWFURLComplete(e:Event):void 
{
              //var loaderInfo:LoaderInfo = LoaderInfo(e.target);
              //var byteArray:ByteArray = loaderInfo.bytes;
               this.stage.addChild(loaderSWFURL);
}

Can someone hep me on this?

Thank you.
