get the event when the loaded movieclip is ready in the right frame

Question

Hi, i'm developing an app that use swf to load elements and add properties to the loaded swf. I use SWFLoader to load the movie and on the COMPLETE event i move the loaded MovieClip to a specific frame and then list its DisplayList. I've discovered that if i traverse the list soon it's note loaded. Maybe it's cleaner with code:

loader.addEventListener(Event.COMPLETE, function(evt:Event):void{
    var mc:MovieClip = MovieClip(loader.content);
    mc.gotoAndStop(frameNumber);
    for(i = 0; i < mc.numChildren; i++){
         trace(mc.getChildAt(i));
    }
}

I miss some children from the loaded swf and in some cases i get null values. Now i've added a Timer() that wait 250ms before listing the display list and works but it's very slow and inefficient.

The other strange behaviour is that with the previous snippet i can't get some MovieClip, even with the Timer in place. I had to insert a function in the loaded swf like this:

function getItems():Array{
    var res:Array = [];
    for(var i:uint = 0; i < this.numChildren; i++){
        res.push(this.getChildAt(i));
    }
    return res;
}

To retrieve the correct list of children.

Thanks a lot

Are you using the Loader class, if so, you need to add the event listener to the loader's contentLoaderInfo property, not the loader object itself. It is a very common mistake.

loader.contentLoaderInfo.addEventListener(Event.COMPLETE, function(evt:Event):void{
    var mc:MovieClip = MovieClip(loader.content);
    mc.gotoAndStop(frameNumber);
    for(i = 0; i < mc.numChildren; i++){
         trace(mc.getChildAt(i));
    }
}
