前几天做分组，老是遇到问题，后来经过测试，找到了解决方法。
model中：
Ext.define('Sharera.model.community.Topic', { extend: 'Ext.data.Model', idProperty: 'id', fields: [ {name:'id',type:'long'}, {name:'title',type:'string'}, {name:'community.name',type:'string'}, {name:'community.id',type:'long'}, {name:'community',type:'object'}, {name:'creator',type:'object'}, {name:'participator',type:'object'}, {name:'created',type:'string'}, {name:'modified',type:'string'}, {name:'enabled',type:'boolean'} ]}); store： /** * The com.sharera.web.Topic store definition */Ext.define('Sharera.store.community.Topic', { extend: 'Ext.data.Store', autoLoad: false, autoSync: false, fields: ['id','title','community','creator','participator','created','modified','enabled'], baseUrl : context+'api/topic', sorters: {property: 'created', direction: 'DESC'}, groupField: 'community.name', proxy: { type: 'rest', url: context+'api/topic', model: 'Sharera.model.community.Topic', reader : { type : 'json' }, writer : { type : 'json' }, listeners : { exception : function(proxy, response, operation) { if (operation) { Ext.Sharera.error("错误",operation.error.statusText); } else { // May be a proxy error... } }, load:function(store,records,successFull,o){ store.sort([{property : 'community',direction: 'ASC'}]); } } }, setUrlforForm : function(id) { if(id==undefined || id==null) this.proxy.url = this.baseUrl; else this.proxy.url = this.baseUrl + "/" + id + ".json"; }, setUrlforQuery : function(name) { if (name == null) name = 'list'; this.proxy.url = this.baseUrl + "/" + name + ".json"; }, setUrlforQuery4Ext : function(name) { if (name == null) name = 'listext'; this.proxy.url = this.baseUrl + "/" + name + ".json"; }}); grid中的代码：
