Aptana给出了JSON格式的错误

Question

格式：

{
    "lastUpdate" : "20/9/2012-12:12",
    "data":[{
        "user" : "_name_",
        "username" : "_fullname_",
        "photoURL" : "_url_"
    }, {
        "user" : "_name_",
        "username" : "_fullname_",
        "photoURL" : "_url_"
    }, {
        "user" : "_name_",
        "username" : "_fullname_",
        "photoURL" : "_url_"
    }]
}

为什么？看来我在接收和处理数据方面没有任何问题。

[EDIT 1]给出错误：语法错误：意外令牌“：”
