加载外部swf时闪存崩溃(这次使用代码示例)

这是在FlashDevelop中创建的AS3项目。它针对Flash播放器10。 运行此代码时遇到一个令人不安的问题:

package 
{
    import flash.display.Loader;
    import flash.display.MovieClip;
    import flash.display.Sprite;
    import flash.events.Event;
    import flash.net.URLRequest;

    public class Main extends MovieClip
    {
        private var loader:Loader;
        private var sprite:Sprite;

        public function Main():void 
        {
            if (stage) init();
            else addEventListener(Event.ADDED_TO_STAGE, init); }

        private function init(e:Event = null):void {
            removeEventListener(Event.ADDED_TO_STAGE, init);

            loader = new Loader();
            loader.contentLoaderInfo.addEventListener(Event.COMPLETE, loadingDone);

            loader.load(new URLRequest('loadIn.swf')); // error occurs when loading this file.
            //loadIn.swf is compiled with all the code in this file but with the loader-parts commented out...

                    // just a Adobe Flash created graphic, no problems loading this one
            //loader.load(new URLRequest('waitingPopup.swf')); 

            //sprite = new Sprite();
            //sprite.graphics.beginFill(0xFF0000);
            //sprite.graphics.drawRect(0, 0, 490, 356);
            //sprite.graphics.endFill();
            //addChild(sprite);
        }
        private function loadingDone(e:Event):void {
            trace(loader.contentLoaderInfo.contentType);        // application/x-shockwave-flash
            trace(loader.contentLoaderInfo.parentAllowsChild);  // true
            trace(loader.contentLoaderInfo.sameDomain);         // true
            trace(loader.contentLoaderInfo.swfVersion);         // 10
            trace(loader.contentLoaderInfo.content);        // [Object Main]

            //this is were everything goes south
            addChild(e.target.content); 
        }
    }
}

现在,我可以从调试窗口收集到的内容,当我尝试调用addChild() - 方法时,swf重新启动自身并在循环中结束。输出窗口中显示的所有内容都是:

[SWF] C:\svn\Development\TestProject\bin\loadIn.swf - 1 797 bytes after decompression.
application/x-shockwave-flash
true
true
10
[object Main]

任何想法会产生如此奇怪的循环和错误?我一直在努力解决这个问题。可能是FlashDevelop中的某种设置或MXMLC编译器的参数?

感谢所有答案!

如果在添加子项之前删除了LoadingDone侦听器,则可能会有所帮助。也许第二个加载的swf的COMPLETE事件冒泡到主剪辑并重新触发另一个负载:

private function loadingDone(e:Event):void {
    loader.contentLoaderInfo.removeEventListener(Event.COMPLETE, loadingDone);
    addChild(e.target.content); 
}

如果它们具有相同的名称且您无法或不想更改名称,请尝试在URLRequest的LoaderContext中使用新的applicationDomain加载该文件:http://www.adobe.com/livedocs/flash/9.0/ActionScriptLangRefV3/flash/system/LoaderContext.html 这应该解决任何冲突。
