Question

please help i am getting this error and could not solve with any of the other methods described in all previous posts with similar topic.

Actually here i am loading a swf myMap onto another swf.
The swf loading works fine, but when try to remove this from stage i get the above said error…

ArgumentError: Error #2025: The supplied DisplayObject must be a child of the caller.
    at flash.display::DisplayObjectContainer/removeChild()
    at actions.classes::MapInteractionManager/unloadSWF()
    at flash.events::EventDispatcher/dispatchEventFunction()
    at flash.events::EventDispatcher/dispatchEvent()

Here’s my as3 code…

 var _swfLoader:Loader;
    var _swfContent:MovieClip;

    loadSWF("myMap.swf");  //loading the swf file here

    function loadSWF(path:String):void {
       var _req:URLRequest = new URLRequest();
       _req.url = path;

       _swfLoader = new Loader();
       setupListeners(_swfLoader.contentLoaderInfo);

       _swfLoader.load(_req);
    }

    function setupListeners(dispatcher:IEventDispatcher):void {
       dispatcher.addEventListener(Event.COMPLETE, addSWF);
       dispatcher.addEventListener(ProgressEvent.PROGRESS, preloadSWF);
    }

    function preloadSWF(event:ProgressEvent):void {
       var _perc:int = (event.bytesLoaded / event.bytesTotal) * 100;
       // swfPreloader.percentTF.text = _perc + "%";
    }

    function addSWF(event:Event):void {
       event.target.removeEventListener(Event.COMPLETE, addSWF);
       event.target.removeEventListener(ProgressEvent.PROGRESS, preloadSWF);

       _swfContent = event.target.content;
       _swfContent.addEventListener("close", unloadSWF);

       main.stage.addChild(_swfContent);
    }

    function unloadSWF(event:Event):void {
       _swfLoader.unloadAndStop();

    main.stage.removeChild(_swfContent);  //getting error when trying to remove swf
       _swfContent = null;
    }


    and close event is as,
    _swfContent.dispatchEvent(new Event("close"));

Please help, I’m stuck.

here with some update,
i updated code as,

function unloadSWF(event:Event):void
{
     if(main.stage.contains(_swfContent))
           main.stage.removeChild(_swfContent);
}

Now the error is gone as it is not entering the if loop!!!???

But still i can see that swf on stage:( plz help

GOT SOLVED…
Thanks everyone for helping…

ToddBFisher did solve it:)

Simply added the _swfLoader to the stage, loaded it, and attached the close listener to it instead of even having a _swfContent. Cut out the middle man and it worked…. Hope this helps…

As I recall .unloadAndStop(); does a bunch of cleanup type things, which you are calling right before. It is possible part of the cleanup is removing it from the display list.

Try calling the removeChild() before calling unlodaAndStop()

function unloadSWF(event:Event):void {
    stage.removeChild(_swfContent);  //getting error when trying to remove swf
    _swfLoader.unloadAndStop();
    _swfContent = null;
}

EDIT

Try simply adding the _swfLoader to the stage, load it, and attach the close listener to it instead of even having a _swfContent. Cut out the middle man and see what happens.
