[/code]
store的数据：{"success":"true","profileList":[{"profileID":"1","profileShare":"Public","profileName":"Default"}]}
提交到后台时，就老是把'profileName'的值提交上去，而不是'profileID'的值，，用hiddenName:'testhidden',了，不知道是不是自己大意了，还是能把是'profileID'的值发到后台

请解答下
谢谢

id/name传的是displayField
hiddenName传的是valueField -- 实际上就是生成一个hidden类型的input

你用firebug看下对应的这个input的值是什么

另外,可以先把tpl等干扰因素去掉先

解决了?
