EXT combbox 下拉问题

1.使用simplestore正常
2.使用远程数据，设置triggerAction:'all'，正常
3.使用远程数据，设置triggerAction:'query',读不出数据
4.使用远程数据，设置triggerAction:'query',在combobox中输入4个字符可加载到数据,但没有筛选功能

先找出是不是服务器的问题
断点跟踪提交到服务器上的参数，
执行结果，
需要返回到页面的值。

再来看是不是EXT哪个地方写错了。

triggerAction 用all表示把下拉框列表框的列表值全部显示出来，如果用query，如果你做了一次选择，第二次再去用，按第一次输入的值，它只显示匹配出来的。
