Alloy Alloy 1.8 升级后数据绑定错误

Question

模特：

exports.definition = {
    config: {
        "columns": {
            "id":"INTEGER PRIMARY KEY AUTOINCREMENT",
            "title":"TEXT",
            "file":"TEXT UNIQUE",
            "desc":"TEXT",
            "media":"TEXT",
            "type":"TEXT"
        },
        "adapter": {
            "type": "sql",
            "collection_name": "downloads",
            "db_name":"downloads.db",
            "idAttribute":"id"
        }
    },

    extendModel : function(Model) {
        _.extend(Model.prototype, {
        });

        return Model;
    },

    extendCollection : function(Collection) {
        _.extend(Collection.prototype, {
        });

        return Collection;
    }
};

请注意第 id 列是 autoincrement。

视图：

<ListItem title:text="{title} - {media}" subtitle:text="{desc}" itemId="{id}" />

请注意，它已绑定到 id 列。

如果我在未指定 id 的情况下调用以下内容（我不必这样做。它是自动递增的）：

collection.create({title:'title',desc:'desc',file:'file',media:'media',type:'type'});

我得到一个错误：

[ERROR] :  Script Error {
[ERROR] :      column = 10;
[ERROR] :      line = 4;
[ERROR] :      message = "Can't find variable: id";

[ERROR] :  }

这只是在升级之后。任何的想法？是我这边的 bug 还是什么东西坏了？

谢谢。
