Extjs gridPanel带参数分页查询的问题

请教各位!

我有一个gridPanel,是根据参数去DB查询数据的,然后显示。
问题是:画面一开始初始化的数据和分页都是对的,参数也能传过去,
但是当我再安“下一页”按钮时,它只把start:10和limit:10传过去了,检索条件的参数确没传过去!

请各位,这种情况都是怎么作的?
谢!!!!

常见问题之一,把你的查询参数放入到store.baseParam中

baseParams : Object

An object containing properties which are to be sent as parameters for every HTTP request.
Parameters are encoded as standard HTTP parameters using Ext.urlEncode.
Note: baseParams may be superseded by any params specified in a load request, see load for more details.
This property may be modified after creation using the setBaseParam method.
