easyui datagrid 弹出窗口空白的解决方法

我的主页面,代码如下:

Javascript代码

//添加数据弹出窗口
$(function(){            
    addDataWin = $('#addData-window').window({                    
        href:'${basePath}/page/marketPlat2/addData/addData.jsp?workId=${workId}year=${year}&month=${month}   &quarter=${quarter}&businessType=${businessType}&type=${type}',
    title:'添加数据',
    left:'100px',
    top:'70px',
    closed: true,
    modal: false,
    cache: false,
    minimizable:false,
    maximizable:false,
    collapsible:false,
    shadow: false
    });
//添加数据弹出窗口
    function addData(){
        addDataWin.window('open');                       
    }
}
//这里只插入了一个datagrid的部分代码,就是点击这个按钮,就会新调用addData()方法;
{
    id:'add',
    text:'新增',
    iconCls:'icon-add',
    handler:addData
}
 //关闭弹出窗口
function closeWin(myWin) {
    myWin.window('close');
                 
};    

Html代码

<!-- 弹出窗口:添加数据 -->
<div id="addData-window" title="添加数据" style="510px;height:300px;font-size: 16">
</div>

第一个弹出窗口代码为:

效果图为:

第二个弹出窗口

正常操作步骤:
1、点击新增按钮时(第一个图片),
2、打开第一个弹出窗口“添加数据弹出窗口”(第二个图片),
3、当我在添加数据弹出窗口中点击“查询”按钮时,弹出第二个弹出窗口,查询出数据显示出来(第三个图片);
现在问题是:
如果我按上面顺序打开后,没有做任何操作,再关闭2、3步骤的弹出窗口,再重复上面1-3的步骤时,第3步的页面打开没有数据,直接显示空白,如果把主页面刷新一下,又正常了,但是打开第一层、第二层弹出窗口,再关闭,然后再点击新增按钮,再加开第一层弹出窗口,没有任务问题,打开第二层弹出窗口后,又出现空白。

我查看了一下,没有缓存,而且第3步的datagrid方法也在后台debug调用了,打开第二层弹出窗口时,后台的方法也有执行,也有返回json字符串数组,在第3步的页面jsp中我也alert()打印过了,都有数据,就是table显示不出来,请教一下高手这是哪 里出问题了?如何解决?
