Loading external swf into Air App

[SFMltd]

Hi All,

I'm building an Adobe Air App for desktop and am having problems loading an external swf. Every time i try to load i get:

SecurityError: Error #2070: Security sandbox violation........ cannot access Stage owned by app....blah blah

The file that is being loaded is in a local directory, but as i understand its in a different 'sandbox' which is a security risk.

Is there any way around this?!

Any help would be much appreciated

Many Thanks

Matt

you're using a loadercontext, correct?  is it using currentDomain?

Hi Kglad,

I have tried using a loaderContext with currentDomain but I couldn't get it to work. Could you give me an example of the correct approach? Perhaps I was using it wrongly with the loader instance.

Many Thanks

Matt

var loaderContext=new LoaderContext(true,ApplicationDomain.currentDomain);  //<-if you're loading a swf from a different domain, load policy file.  ie, you need a policy file on the loaded swf's server

loaderContext.securityDomain=securityDomain.currentDomain;  // "  ".

var loader:Loader=new Loader();

loader.load(new URLRequest('yourswf.swf',loaderContext);

Hi Kglad, Thanks for the Example.

if i run my class with securityDomain = SecurityDomain.currentDomain; then it throws this error: SecurityError: Error #2142: Security sandbox violation: local SWF files cannot use the LoaderContext.securityDomain property.

The swf file im trying to load is stored locally so i guess this error makes sense. However if i comment out that line i get the same "cannot access Stage owned by app" error?

See below for class:

package  {

  import flash.display.MovieClip;

  import flash.filesystem.File;

  import flash.events.Event;

  import flash.net.FileReference;

  import flash.events.MouseEvent;

  import flash.display.Loader;

  import flash.net.URLRequest;

  import flash.system.LoaderContext;

  import flash.system.ApplicationDomain;

  import flash.system.SecurityDomain;

  public class assetPreview extends MovieClip {

  private var loader:Loader;

  private var mainSWF:MovieClip = new MovieClip();

  public function assetPreview() {

  addEventListener(Event.ADDED_TO_STAGE, initialise);

  }

  public function initialise(e:Event):void

  {

  removeEventListener(Event.ADDED_TO_STAGE, initialise);

  var allowSWF:LoaderContext = new LoaderContext(true,ApplicationDomain.currentDomain);

  allowSWF.securityDomain = SecurityDomain.currentDomain;

  loader = new Loader();

  loader.load( new URLRequest(settingsXML.pathToSWF),allowSWF);

  loader.contentLoaderInfo.addEventListener(Event.COMPLETE, viewPreview);

  }

  public function viewPreview(e:Event):void

  {

  addChild(mainSWF);

  mainSWF.addChild(loader);

  }

  }

}

that's why i added those comments about the swf's domain.  for locally loaded swfs, use:
