我唯一可以想到的是，我的Flash Media Server 4 Developer正在加载，不会计算我发送的元数据。

任何想法都会大有帮助。

private function sendMetadata():void {


                 infotxt.text += 'called';
                trace("sendMetaData() called")
                myMetadata = new Object();
                myMetadata.customProp = "This message is sent by @setDataFrame.";
                myMetadata.customOther = cueHolder;
                ns.send("@setDataFrame","onMetaData",myMetadata);
            }

这里是我的onMetaData函数

public function onMetaData(info:Object):void { 
                trace("caught");
                infotxt.text = 'caught';
                var key:String;
                for (key in info){ 
                    outputWindow.text +=(key + ": " + info[key] + "\n"); 
                }
                //cueHolderReturn = info.customOther;
                 for (var i:int = 0; i < info.customOther.length; i++) 
                {
                    infotxt.text += info.customOther[i]
                } 

                //infotxt.text = info.customOther[0];




            }
