ext 与dwr 结合问题（Grid Proxy）

Question

现在使用 ext3.0 与dwr 结合 显示分页的Grid ，使用 httpproxy 代理 没有任务 问题。
病切 通过测试 dwr 调用 服务方法也测试通过，但是 ，结合这使用 用dwrproxy做代理就除问题 ，
错误：

现在可以使用dwr将数据显示出来了 但是 翻页的时候 不行，还是显示第一页的数据，start值传过去后还是0 不知道是哪里出问题了

js:
function createGrid(){
var cm = createColumnModel();
var ds = new Ext.data.Store({
proxy:new Ext.data.DWRProxy(SiteManager.qrySites,startParams),

reader:new Ext.data.DWRJsonReader({

//proxy: new Ext.data.HttpProxy({url:url}),
//reader: new Ext.data.JsonReader({
totalProperty: 'totalProperty',
root: 'root'
},[
{name: 'no'},
{name: 'siteName'},
{name: 'updDate'},
{name: 'addDate'}]
) ,remoteSort:false
});
ds.load({params:startParams});
//以下是表格翻页时，动态传递参数部分
ds.on('beforeload', function() {
pageChange();
Ext.apply(this.baseParams,{loginNo:loginNo});
});
ds.on('load', function() {
});
var pageToolBar = new Ext.PagingToolbar({
pageSize:pageSize,
store: ds,
displayInfo:true,
displayMsg: '显示第 {0} 条到 {1} 条记录，一共 {2} 条',
emptyMsg: "没有记录"
});
pageToolBar.on('change',function(obj,pageData){
//alert(JSON.stringify(pageData));
curPage = pageData.activePage;
})

    var grid = new Ext.grid.GridPanel({ 
            el: 'gridDiv', 
            title:"站点管理",
            loadMask: true,
            height:220,
            ds: ds, 
            cm: cm,
            viewConfig:{
                columnsText:"显示/隐藏",
                sortAscText:"正序排列",
                sortDescText:"倒序排列",
                forceFit:true
            },
            bbar: pageToolBar
    }); 
    grid.render(); 
    //grid.getSelectionModel().selectFirstRow();
    grid.getSelectionModel().on('rowselect', function(sm, rowIdx, r) {
        var arr = r.data.siteName.split('#');
        Ext.get('siteId').dom.value = arr[0];
        Ext.get('siteUrl').dom.value = arr[1];
        //alert(r.data.siteName);
    });
}
//创建表头
function createColumnModel(){
    var sm = new Ext.grid.CheckboxSelectionModel({header:'',singleSelect:true,fixed:true});
    var cm = new Ext.grid.ColumnModel([
    //new Ext.grid.RowNumberer({header:"序号",width:30,fixed:true}),//自动行号
    {
        header:"序号",
        dataIndex:"no",
        sortable:true,
        fixed:true,
        width:40
    },
    sm,
    {
        header:"站点名称",
        dataIndex:"siteName",
        sortable:false,
        renderer:rendererSiteName
    },{
        header:"修改时间",
        dataIndex:"updDate",
        sortable:true
    },{
        header:"添加时间",
        dataIndex:"addDate",
        sortable:true
    }]);
    cm.defaultSortable = true; 
    return cm;
}

java dwr后台服务方法：
sitRequest（start,limit,loginNo属性）
/* (non-Javadoc)
* @see com.sitechasia.webshop.sitemaketool.service.ISiteManagerService#qrySites(com.sitechasia.webshop.sitemaketool.model.SiteQryRequest)
*/
public String qrySites(SiteQryRequest sitRequest){
try {
initRequest(sitRequest);
List allData = getTotalResult(sitRequest);
int totalCount = allData.size();
List curData = selRequieredSiteData(allData,sitRequest);

        return transferJson(curData,totalCount,sitRequest);
    } catch (RuntimeException e) {
        e.printStackTrace();
    }
    return "";
}
