Flex 多线程 求解

Flex 多线程 求解 在线等
在网上看到 FLex 用 AsyncThreading_2.1.swc 可以实现多线程

地址如下：http://blog.sina.com.cn/s/blog_4cfe78830100imuo.html

我自己写的代码 如下

Java code

package com.thread{    import com.symantec.premiumServices.asyncThreading.abstract.AbstractAsyncThread;    import com.symantec.premiumServices.asyncThreading.interfaces.IAsyncThreadResponder;    public class AsyncThreading extends AbstractAsyncThread implements IAsyncThreadResponder    {        public function AsyncThreading()        {            super();            super.priority = super.RUN_LEVEL_REAL_TIME;                    }        public function execute():void{                    }    }}

但是 我的代码里执行 var threading:AbstractAsyncThread=new AsyncThreading();的时候就报错

报错信息：
TypeError: Error #1009: Cannot access a property or method of a null object reference.

在线等 求解！最好能贴出一段Flex 多线程的 代码 谢谢了！

[解决办法]
Flex绝对没有多线程概念！

就算有也只是模拟多线程！
[解决办法]
错误的意思是 有一个参数 或者方法为空 LZ自己好好检查一下 是不是调错方法了
[解决办法]
lz要做聊天功能吗？

他的博客上写过，不知道对lz有没有帮助
[解决办法]
没有多线程的，仿的我都没看到过，有空研究下...
[解决办法]
Flex3应该是可以的吧
