如下代码（完整的，粘贴就可运行）的分页不成，求解~
右部隐去了，见下面截图

[解决办法]
store = new Ext.data.JsonStore({ // gird的数据
root : 'info',
totalProperty : 'count',
fields : create,
proxy : new Ext.data.HttpProxy({
url : contextPath + '/dic/parts/partsAction!getPartsList.do'
})
});
貌似必须声明 totalProperty 属性
[解决办法]
totalProperty: 'maxPage',
数据源里没有一共多少条，你在ds中加上这个试试！
