刚看了一下，应该是异步问题。 combobox加载完成时，其store的load过程并未完成。用autoLoad：true 代替cityStore.load()试一下

JsonReader 放到 proxy 里 var cityStore = Ext.create('Ext.data.Store', { model: 'City', proxy: { type: 'ajax', url : 'role_findRoleByPage.action', reader: { type: 'json', totalProperty:'totalCount', root:'list' } } });

没用....
