Api extjs网格dnd插件不会创造价值

我复制了这个示例，并定义了我的模型和存储。

如您所见，我将设置api创建、更新和销毁操作。但当我拖放网格行时，我的存储只执行销毁和加载操作。我不明白为什么商店不执行任何创建。。。在另一个我有一个网格的应用程序中，自动同步工作正常。

默认为false，将其设置为true

var secondGridStore=Ext.create（'Ext.data.Store'{ 模型：“数据对象” 自动同步：真

---

});

至少在4.1.1中，问题是您正在拖动的记录的

幻影设置为false。处理该删除的代码如下所示，您将看到，在将丢弃的记录插入到新存储之前，没有任何东西可以将丢弃的记录设置为true

这似乎是一个bug

Ext.define('Ext.grid.ViewDropZone', {
    extend: 'Ext.view.DropZone',

    handleNodeDrop : function(data, record, position) {
        var view = this.view,
            store = view.getStore(),
            index, records, i, len;

        // If the copy flag is set, create a copy of the models
        if (data.copy) {
            records = data.records;
            data.records = [];
            for (i = 0, len = records.length; i < len; i++) {
                data.records.push(records[i].copy());
            }
        } else {
            /*
             * Remove from the source store. We do this regardless of whether the store
             * is the same bacsue the store currently doesn't handle moving records
             * within the store. In the future it should be possible to do this.
             * Here was pass the isMove parameter if we're moving to the same view.
             */
            data.view.store.remove(data.records, data.view === view);
        }

        index = store.indexOf(record);

        // 'after', or undefined (meaning a drop at index -1 on an empty View)...
        if (position !== 'before') {
            index++;
        }
        store.insert(index, data.records);
        view.getSelectionModel().select(data.records);
    }
});

Ext.define（'Ext.grid.ViewDropZone'{
扩展：“Ext.view.DropZone”，
handleNodeDrop：功能（数据、记录、位置）{
var view=this.view，
store=view.getStore（），
索引，记录，i，len；
//如果设置了复制标志，请创建模型的副本
if（data.copy）{
记录=数据记录；
data.records=[]；
对于（i=0，len=records.length；i
我将其设置为true。那没用。正如我之前所说：销毁和加载工作很好，但创建忽略。。。
Ext.define('Ext.grid.ViewDropZone', {
    extend: 'Ext.view.DropZone',

    handleNodeDrop : function(data, record, position) {
        var view = this.view,
            store = view.getStore(),
            index, records, i, len;

        // If the copy flag is set, create a copy of the models
        if (data.copy) {
            records = data.records;
            data.records = [];
            for (i = 0, len = records.length; i < len; i++) {
                data.records.push(records[i].copy());
            }
        } else {

             */
            data.view.store.remove(data.records, data.view === view);
        }

        index = store.indexOf(record);

        // 'after', or undefined (meaning a drop at index -1 on an empty View)...
        if (position !== 'before') {
            index++;
        }
