推荐答案

内存代理不能使用常规的寻呼机制。您需要一个特殊的用户扩展类： http： //docs.sencha.com/ext-js/4-1/#!/api/Ext.toolbar.Paging 向下滚动到使用本地数据分页部分。

Memory proxy wont work with a regular paging mechanics. You need a special user extension classes: http://docs.sencha.com/ext-js/4-1/#!/api/Ext.toolbar.Paging Scroll down to "Paging with Local Data" section.
