Hi Andrew,

The instantiation of my SWFLoader:

if ( !_swfLoader ) {
_swfLoader = new SWFLoader();
_swfLoader.loaderContext = new LoaderContext( true, null, SecurityDomain.currentDomain );
_swfLoader.scrollRect = new Rectangle( 0, 0, 740, 370 );
_swfLoader.autoLoad = true;
_swfLoader.addEventListener( Event.COMPLETE, playFlash );
}

_swfLoader.source = _source;

I allready did this in de beginning, only then I also set trustContent to true and used ‘null’ for security domain. This is basicly the same as your code, except the ApplicationDomain part, but that didn’t gave me an issue.

Would they be best off using a Module, instead of a full blow Flex app, inside another?

Flex 4 b2 (10485) simple loading sub-app with Externalizing application classes. Does anyone has a working example ?
I am trying this with the most simple application and I am getting rte “Could not find compiled resource bundle ‘components’ for locale ‘en_US’.” ???

Hi Gertjan,

Oh, loading from a different domain will hit security sandbox issues! You should be able to get around it like you have above… but here’s some code in a little more detail.

The code assumes you set your mx:SWFLoader id=”swfLoader”

import flash.system.SecurityDomain;
import flash.system.ApplicationDomain;

var context:LoaderContext = new LoaderContext();
context.securityDomain = SecurityDomain.currentDomain;
context.applicationDomain = new ApplicationDomain();
swfLoader.loaderContext = context;
swfLoader.source = “http://otherdomain.com/RemoteApp.swf”;

Interested to know if the above works for you. Set this up before you set the source for the SWFLoader.

Hi Andrew!

Thanks for your post and your effort. I really appreciate it!

But, what you are describing here is exact what I came up with. But it threw a SecurityError.

The .swf that I’m loading is located on a different domain than the parent. So I tried some security settings (I really should dive in more, I know) and ended up with:

_swfLoader.trustContent = true;
_swfLoader.loaderContext = new LoaderContext( true, null, null );
(and as it turns out trustContent is ignored when loaderContext is manually set)

This worked fine when I tested my main .swf on my machine (still grabbing the loaded .swf from the www).
But online it threw a SecurityError when I tried to cast _swfLoader.content to my interface (even when I tried casting it to a SystemManager).

Now my _swfLoader just uses:
_swfLoader.loaderContext = new LoaderContext( true, null, SecurityDomain.currentDomain );

Now it throws a SecurityError offline, but online everything works as expected. (which I like!).

I hope it makes some sense… if not, (and if you’re interested) I’ll explain in more detail.

Again, thanks for your help!
