sharedObject远程文本交互的问题。10

用sharedObject做实事文本交流时，两个页面不能同时获取共享信息，总有一个页面是空白，求大神们指点。服务器端用的是FMS4.5版，没有代码。

代码：

<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600" creationComplete="init()">
