AS3: Removing child throws error

Posted on 2008-10-24
Last Modified: 2013-11-11
Here's what I'm trying to do:
1. Load swf
2. Add children movieclips to swf
3. click one of the children movieclips
4. unload swf and start all over again

However I keep getting the error "The supplied DisplayObject must be a child of the caller". Even when I simplify the code down to this:

function loadSwf(newSwf) {
            swfLoader.load(new URLRequest(newSwf));
              swfLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, onSwfLoad);
            function onSwfLoad(e:Event) {
                  curSwf =;

function unloadSwf() {

I continue to get the error. What am I doing wrong? Argh!

The following works:


var swfLoader:Loader = new Loader();
var curSwf:MovieClip = new MovieClip();
function loadSwf(newSwf) {
	swfLoader.load(new URLRequest(newSwf));
	swfLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, onSwfLoad);
function unloadSwf() {
function onSwfLoad(e:Event) {
	curSwf =;
