this.fields.get(c) is undefined

今天在做项目的时候碰到这个问题,和大家一起分享:
源代码:大家一定需要注意我的Store中的sortInfo:
<script type="text/javascript">
             Ext.onReady(function(){
                 
                 Ext.QuickTips.init();
                 
                 //别名
                 var xg=Ext.grid;
                 
                 //创建一个ArrayReader
                 var reader=new Ext.data.ArrayReader({},[
                   {name:"name",type:"string"},
                   {name:"age",type:"int"},
                   {name:"empno",type:"int"},

                   {name:"deptno",type:"int"}
                 ]);
                 
                 //创建一个store
                 var store=new Ext.data.GroupingStore({

                   groupField:"deptno"  //根据部门来分组
                 });

                 }
