关于EXTJS PagingToolbar分页的问题

[良才2015]

可以查询出第一次分页的结果，并展示到前台，但是相关信息并没有关联上，如第{0} 到 {1} 条数据 共{2}条显示不了。只显示“没有数据”。
前台代码如下：

	//初始化grid 
	var grid = null; 
	//查询信息 
	var store = new Ext.data.Store({ 
	//proxy: new Ext.data.HttpProxy({url:'../system/sysparamList!query.icode?flag=extjs&recordCount=<s:property value="pageAttribute.recordCount"/>&pageCount=<s:property value="pageAttribute.pageCount"/>&pageNo=<s:property value="pageAttribute.pageNo"/>&maxResults=<s:property value="pageAttribute.maxResults"/>&startPosition=<s:property value="pageAttribute.startPosition"/>'}),
	proxy: new Ext.data.HttpProxy({url:'../system/sysparamList!query.icode'}),
	reader:new Ext.data.JsonReader({ 
		root:'jsonarray',
		totalProperty:'totalCount',
		id:'paramid'
			}, 
		storeRecord),
	method:'post'
	}); 

	grid = new Ext.grid.GridPanel({ 
	renderTo:"mainDiv", //grid查询结果指向显示的div层 
	title:"用户查询结果", //grid标题 
	autoHeight : true,
	cm:colM, //定义的列 
	store:store, //定义的数据源 
	bbar: new Ext.PagingToolbar({   
		                pageSize: 20,   
		                store: store,   
		                params : {
		                	start : 'start',
		                	limit : 'limit'
		                	},
		                displayInfo: true,   
		                displayMsg: '第{0} 到 {1} 条数据 共{2}条',   
		                emptyMsg: "没有数据"   
		           })   
			 
	}); 

	store.load({params:{start:0, limit:20}});   

后台代码如下：

			db = new DBOperation();
			dao = new SysparamDAO(db);
			sysparamList = doQuery();

			
			
			
			
			response.setHeader("Cache-Control", "no-cache");
			response.setContentType("text/json;charset=UTF-8");
			JSONArray json = JSONArray.fromObject(sysparamList);
			String jsonarray = json.toString();
			jsonarray = "{\"totalCount\":\"" + sysparamList.size()+ "\",\"jsonarray\":" + jsonarray + "}";
			System.out.println(jsonarray);
			response.getWriter().write(jsonarray);

json数据格式如下:

{"totalCount":"20","jsonarray":[{"data":"","fmt":"","gcode":"TRVL_DORM","id":469,"mcode":"0","mname":"酒店","scope":0,"sort":0},{"data":"","fmt":"","gcode":"TRVL_TRAFFIC","id":472,"mcode":"0","mname":"飞机","scope":0,"sort":0},{"data":"","fmt":"","gcode":"PRV_MARRY","id":289,"mcode":"0","mname":"未婚","scope":0,"sort":0},xxx,xxx,xxx……]}

//displayMsg: '第{0} 到 {1} 条数据 共{2}条',
注释掉试试
