我已经尝试了所有来源，仍然无法找到解决此问题的任何答案。我正在运行Adobe Flash CS6 AS3 每当我运行脚本时，我得到此输出并且文件无法正常运行。在发布的文件中，swf文件未完全显示，这意味着外部.swf文件未安装在contentContainer中。
我的代码是这样的：

var _swfLoader:Loader;
var _swfRequest:URLRequest;


var _swfPathArr:Array = new Array("Slide1.swf", "Slide2.swf", "Slide3.swf");

var _swfClipsArr:Array = new Array();
var _swfTempClip:MovieClip;
var _loadedSWFs:int;
var contact_btn:SimpleButton;
var news_btn:SimpleButton;
var portfolio_btn:SimpleButton;

startLoading(_swfPathArr);

function startLoading(pathArr:Array):void {
    _swfLoader = new Loader();
    _swfRequest = new URLRequest();

    loadSWF(pathArr[0]);
}


function loadSWF(path:String):void {
    setupListeners(_swfLoader.contentLoaderInfo);

    _swfRequest.url = path;
    _swfLoader.load(_swfRequest);
}

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

function currentSwfProgress(event:ProgressEvent):void {
    var _perc:int = (event.bytesLoaded / event.bytesTotal) * 5;
   // swfPreloader.percentTF.text = _perc + "10%";
}


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

    _swfTempClip = event.target.content;
    _swfTempClip.customID = _loadedSWFs;
    _swfClipsArr.push(_swfTempClip);

    if(_loadedSWFs <_swfPathArr.length - 1) {
        _loadedSWFs++;
        loadSWF(_swfPathArr[_loadedSWFs]);
    } else {
        _swfLoader.unloadAndStop();
        _swfLoader = null;
        onCompletePreloading();
    }
}

function onCompletePreloading():void {
    contentContainer.addChild(_swfClipsArr[0]);

   news_btn.enabled = true;
   contact_btn.enabled = true;
   portfolio_btn.enabled = true;
    news_btn.addEventListener(MouseEvent.CLICK, setContent);
    portfolio_btn.addEventListener(MouseEvent.CLICK, setContent);
    contact_btn.addEventListener(MouseEvent.CLICK, setContent);
}

function setContent(event:MouseEvent):void {
    var _swfToAdd:MovieClip;

    switch(event.target.name) {
        case "news_btn":
        _swfToAdd = _swfClipsArr[0];
        break;

        case "portfolio_btn":
        _swfToAdd = _swfClipsArr[1];
        break;

        case "contact_btn":
        _swfToAdd = _swfClipsArr[2];
        break;
    }

    contentContainer.removeChildAt(contentContainer.numChildren-1);
    contentContainer.addChild(_swfToAdd);
    trace(_swfToAdd.customID);
}

当加载的SWF包含“TLF Text”时，我常常遇到此问题。那么修复？在加载的SWF“经典文本”中创建“全部”文本字段，希望您的问题能够得到解决。

PS。从FLA文件中清除所有TLF文本的简便方法是将文档脚本从ActionScript 3.0更改为2.0。由于TLF Text仅支持3.0，因此它们将立即更改回经典文本，然后再将脚本更改回3.0。：）
