RemoteObject在同一页面发送两次后台请求返回值处理

项目是用的flex3+Spring3+hibernate3.6+blazeds，全用注解写的，在同一页面发送两次后台请求，总是报[RPC Fault faultString="java.lang.StackOverflowError : null" faultCode="Server.Processing" faultDetail="null"]错误，代码如下：

既然你都已经获得了result了 你可以绑定一个数据源 把result赋给那个数据源 数据源发生了变化 页面上的内容 会自动变化的

有很多方式可以显示result的值 关键是只要你获得了页面控件的引用后 你就可以为所欲为

是内存溢出了嘛 把应用服务器的内存调大一点试试

估计出现死偱环导致内存溢出了

这样啊 如果是一个RO对象 请求两次 flex是无法辨别返回结果的 需要使用 异步调用令牌
AsyncToken 对象 来唯一的 绑定请求 AsyncToken对象的使用方法可以看那一下api

我这里有一个 AsyncToken对象的小例子 你可以参考一下
是调用一个天气的WebService
package services.weatherwebservice
{
import flash.events.Event;

import mx.controls.Alert;
import mx.rpc.AsyncToken;

import scripts.MyResp;

public class WeatherWebService extends _Super_WeatherWebService
{

public function WeatherWebService(){
    var myRep:MyResp = new MyResp();
    var token:AsyncToken = this.getWeatherbyCityName("石家庄");
    token.addResponder(myRep);//myRep必须是一个IResponse类型的对象 来接受返回的结果
}

}

}

package scripts
{
import mx.controls.Alert;
import mx.rpc.IResponder;

public class MyResp implements IResponder
{
    public function MyResp()
    {

    }

    public function result(data:Object):void
    {
        data.Result是返回的结果
    }

    public function fault(info:Object):void
    {
        Alert.show("Error");
    }
}

}

调试,跟踪是什么原因导致死偱环
是否是某个变量值被意外改变导致代码没法跳出偱环等

callLaterDispatcher方法的代码呢？ 看一下

我flex的经验也不多 以后多多交流 :D
