Loading local content in StageWebView (file URI scheme) not working, bug?

Hey there!

I'm trying to load some local content inside a StageWebView but it looks like it's not working. Here are the docs about this feature.

I think I'm doing it the way I should but I may be wrong... Someone knows how?

Here's my code:

package {
     import flash.display.Sprite;
     import flash.display.StageAlign;
     import flash.display.StageScaleMode;
     import flash.events.ErrorEvent;
     import flash.events.Event;
     import flash.events.LocationChangeEvent;
     import flash.events.StageOrientationEvent;
     import flash.filesystem.File;
     import flash.geom.Rectangle;
     import flash.media.StageWebView;
     import flash.net.URLRequest;
     
     import net.tw.util.air.DownloadHelper;
     
     public class MobileSWFDownloader extends Sprite {
          protected var _downloader:DownloadHelper;
          protected var _swv:StageWebView;
          
          public function MobileSWFDownloader() {
               super();
               
               stage.align = StageAlign.TOP_LEFT;
               stage.scaleMode = StageScaleMode.NO_SCALE;
               
               _downloader=new DownloadHelper(new URLRequest('http://toki-woki.net/lab/eM/test.html'), File.applicationStorageDirectory.resolvePath('local.html'));
               _downloader.stream.addEventListener(Event.COMPLETE, onDownloaded);
               _downloader.start();
          }
          protected function onDownloaded(e:Event):void {
               _swv=new StageWebView();
               _swv.addEventListener(ErrorEvent.ERROR, trace);
               _swv.addEventListener(LocationChangeEvent.LOCATION_CHANGE, trace);
               _swv.stage=stage;
               _swv.loadURL('file://'+_downloader.destination.nativePath);
               placeWebView();
               stage.addEventListener(StageOrientationEvent.ORIENTATION_CHANGE, placeWebView);
          }
          protected function placeWebView(e:Event=null):void {
               _swv.viewPort=new Rectangle(0, 0, stage.stageWidth, stage.stageHeight);
          }
     }
}

And here's the output:

[SWF] MobileSWFDownloader.swf - 4,161 bytes after decompression
[LocationChangeEvent type="locationChange" bubbles=false cancelable=false eventPhase=2 location="file:///data/data/air.fr.edumedia.MobileSWFDownloader.debug/fr.edumedia.MobileSWFDownloader.debug/Local Store/local.html"]

Problem is: the StageWebView remains blank and doesn't seem to load anything...

Any idea why?

The DownloadHelper class is a simple utility that downloads a remote file and stores it locally, available here.

Thanks!
