ExtJS Store Destroy 事件提交

Question

当我想从商店中删除多个项目而不刷新我的页面时遇到问题。我第一次删除事件时，一切正常，正如您可以从这个 Fiddle 片段中看到的那样：

551   200   HTTP   localhost:52543   /api/Appointments/Destroy?_dc=1442940419083   140   no-cache; Expires: -1   application/json; charset=utf-8   chrome:157528

数据：

{ "Id":1749644,"StartDate":"2015-09-22T01:00:00+02:00","EndDate":"2015-09-22T03:00:00+02:00","ResourceId":9,"PreviousResourceId":0,"Name":"","Cls":""}

但是，如果我想随后删除其他项目（不刷新页面），就好像事件存储不接受或理解先前删除的记录已被处理：

[
 { Id":1749644,"StartDate":"2015-09-22T01:00:00+02:00","EndDate":"2015-09-22T03:00:00+02:00","ResourceId":9,"PreviousResourceId":0,"Name":"","Cls":""},
 {"Id":1749656,"StartDate":"2015-09-22T10:45:00+02:00","EndDate":"2015-09-23T16:00:00+02:00","ResourceId":20,"PreviousResourceId":0,"Name":"test","Cls":""}
]

如果仔细观察，您会发现第二次调用中也出现了相同的事件，而这不应该！除此之外，一切都很完美：Web API 在每一次 destroy 调用之后被调用（因此是在每次页面请求之后的第一次）。第一次调用后，Web API 仍被调用，但绑定现在由于意外输入而损坏：它收到一个集合，但它只需要 1 个项目。

这是撕裂：

Ext.define('SchedulerApp.store.EventStore', {
extend: "Sch.data.EventStore",
autosync: true,
batch: false,
proxy: {
    type: 'ajax',
    api: {
        create: '/api/Appointments/Add',
        update: '/api/Appointments/Update',
        destroy: '/api/Appointments/Destroy'
    },
    reader: {
        type: 'json'
    },
    writer: {
        type: 'json',
        writeAllFields: true
    }
},
listeners: {
    load: {
        fn: function (store, records, successfull) {
        }
    },
    create: {
        fn: function (store, records, successfull) {

        }
    },
    add: {
        fn: function (store, records, successfull) {
            //store.sync();
        }
    },
    update: {
        fn: function (store, records, successfull) {
            var previousResource = records.previous.ResourceId;
            records.data.PreviousResourceId = previousResource;
            records.store.sync();
        }
    },
    destroy: {
        fn: function (store, records, successfull) {
        }
    },
    remove: {
        fn: function (store, records, successfull) {
            store.sync();
        }
    }       
}

});

我需要弄清楚如何 'accept' 一条 updated/inserted/removed 记录。这是一个相当独立的问题，因此此处发布的所有其他代码都是无用的信息。

原来我确实错过了商城的承诺功能。在回调的成功方法中，我添加了提交，问题消失了！
