Jeff from Custom Logic posted on the Flash Lite mailing list about a problem with MovieClipLoader. Basically, if you remove the MovieClip via removeMovieClip that is used in the load operation for the MovieClipLoader.loadClip, as soon as the image loads, you’ll get a “Unable To Load Data” error. For some reason this race condition is handled fine in Flash Player 9 and below, as well as the Flash Lite emulator in Flash 8, but not in Flash Lite 2.

Solution is to encapsulate the load operation & removing of the MovieClip in a class that generates an event upon success since it cannot happen immediately.

Non-class example (tested and works):

function init()
{
        mcl = new MovieClipLoader();
        mcl.addListener(this);
        
        load_btn.onPress = function()
        {
                this._parent.doLoad();
        };
        
        kill_btn.onPress = function()
        {
                this._parent.doKill();
        };
        
        // keep state
        abortFurtherLoading = false;
        isLoading = false;
        
        fscommand2("FullScreen", true);
        
}

function doLoad()
{
        // only load if we aren't already doing so
        if(isLoading == false)
        {
                isLoading = true;
                if(image_mc) image_mc.removeMovieClip();
                createEmptyMovieClip("image_mc", 0);
                mcl.loadClip("http://www.some.com/image.jpg", image_mc)
        }
}

function onLoadInit(p_mc)
{
        isLoading = false;
        // if we should abort, go ahead and remove
        // the clip
        if(abortFurtherLoading)
        {
                abortFurtherLoading = false;
                removeTheClip();
        }
}

function doKill()
{
        // if we are loading...
        if(isLoading == true)
        {
                // ...wait till we're done
                abortFurtherLoading = true;
        }
        else
        {
                // ...otherwise, kill immediately
                removeTheClip();
        }
}

function removeTheClip()
{
        image_mc.removeMovieClip();
        delete image_mc;
}

init();
