我想从ExtDirect路由器加载网格数据。结果包含一个应重新配置商店字段的元数据对象。但是我收到以下错误,当我尝试加载我的数据:ExtJS DirectStore中字段的元数据配置

商店本身的配置,如:
var store = new Ext.data.DirectStore({
idProperty: 'id'
,paramsAsHash: true
,directFn: MyApp.Direct.Dashboard.dashboarddata
,root:'data'
,autoLoad: false
,totalProperty:'total'
,fields: [
{name: 'id', mapping: 'id'},
{name: 'type', mapping: 'type'}
]
,baseParams: {
type: this.type,
filters: this.filters
}
});
任何人都可以请帮帮我?这让我疯狂,我看不出我做错了什么。
谢谢!

PS。我正在使用ExtJS 3.3.0
嗯,曾经试过调试ExtJS? :)大量的代码行来通过。无论如何,我认为这是我最好的选择。 – 2011-01-19 21:12:28
