Loading one Robotlegs project to another Robotlegs project

Hi everyone!

I have a little problem. ( At the begining sorry if my English is bad , it's not my native language).
So i made application in RL , and now i have to include that application into another ( which is also made in RL ) .
But include have to be done by loading that smallest one app ( .swf ) into that bigger one, with preserving communication
between both of them ( both are using Events for communicating ). So I can send to small application events from that bigger one.
Important thing is - that i have still possibility to change source code from small application too.
My problem is - that I can't achieve that. I was reading lot of exaples for Modular Utility , but it's mainly for modular applications without loading standalone modules. So i can't find proper solution. Could you help me ? Maybe someone have some exemple ? I would be very gratefull for some help. Thanks !

    Hi Lukas,

    So i made application in RL , and now i have to include that application into another ( which is also made in RL ) .

    This looks like a sub-application to me rather than a module.
    A couple of questions to you:
    Have you tried to communicate between 2 non-rl applications already? Does this work? How are you loading the sub-application, are you using the Loader class?

    If it is a sub-application, then one possible cause of your problem could be the way you set your ApplicationDomain for the loaded swf.

    See this post for more info on ApplicationDomain: http://livedocs.adobe.com/flex/3/html/help.html?content=18_Client_S...
    Loading and managing sub-applications can be pretty annoying sometimes.

    The following code works for a sub-application:
    protected function onLoaderComplete(event:Event):void

    var appDomain:ApplicationDomain=ApplicationDomain.currentDomain;
    var context:LoaderContext=new LoaderContext(false, appDomain);
    var loader:Loader=new Loader();
    loader.loadBytes(urlLoader.data, context);

    sharedEventDispatcher.addEventListener("SubAppToMainAppEvent", onSubAppChanged, false, 0, true);


    protected function sendDataToSubApp():void

    var dynamicEvent:DynamicEvent=new DynamicEvent("MainAppToSubAppEvent");
    dynamicEvent.data="application to subapplication";


    If this doesn’t answer your question, could you please show us the code where you are loading your second application?

    Unfortunatelly it doesn't work like that .. There is no error during compilation. But when application fires - smallest application content doesn't appear at the stage.

    this is a code :

    protected const WALL_PATH:String = "data/small_rl_app.swf";

        public function load():void
            var loader_context:LoaderContext = new LoaderContext(false, ApplicationDomain.currentDomain);
            _loader = new BulkLoader("smallAppLoader");
            _loader.addEventListener(BulkProgressEvent.COMPLETE, loadSuccess);
            _loader.add(WALL_PATH, { id:WALL_PATH, context:loader_context}); 
        protected function loadSuccess(e:BulkProgressEvent):void
            var wall:Sprite = _loader.getSprite(WALL_PATH);

    The code snippet from my previous message works fine on my end, with 2 robotlegs applications, where one is loading the other one as a sub-application.

    So, I don’t think that your issue has anything to do with robotlegs.

    You didn’t answer my question from my previous post: Have you tried to load a sub-application in another application, where both applications are not using robotlegs or any other libraries or frameworks? Just 2 simple applications?

    Could it be that you created your SWFLoader or Loader through actionscript like this:

    private var swfLoader:SWFLoader;

    Then, somewhere in your code:

    var appDomain:ApplicationDomain=ApplicationDomain.currentDomain; swfLoader=new SWFLoader(); swfLoader.addEventListener(Event.INIT, swfLoaded); swfLoader.loaderContext=new LoaderContext(false, appDomain); swfLoader.load(urlLoader.data);

    and you forgot to add it to the display list?
