Actionscript 3 UI组件从Flex到Air

在Flex应用程序中，我找到了一种将目标对象保存为“字符串”的方法

有没有办法读取该文件并在空中显示为UIComponent？
这是我的尝试：

                //var obj:BorderContainer = data.;
                cc = data.readObject();

                //clean up the FileReference instance

                fr = null;
            }

            //called if an error occurs while loading the file contents
            private function onLoadError(e:IOErrorEvent):void
            {

我得到一个错误：

任何解决方案都可以。。。只要有效：）

在写入ByteArray之前，您需要为

BorderContainer

注册一个类别名。否则，对象的类型将无法保留，容器将作为普通对象写入ByteArray

检查以获取有关如何在ActionScript中读取/写入（或使用更常见的术语：序列化/反序列化）强类型对象的详细信息

如果我说得对，您需要在基于Web的应用程序和AIR两个应用程序中注册类别名。
