我编写了一个应用程序，它构建了一个由迭代过滤的用户故事网格。它似乎有效，并且没有错误，但故事列表不完整。一些迭代在网格中缺少一半的故事。所有故事都在同一个项目中。我究竟做错了什么？如果您对如何改进以下代码有任何建议，请告诉我。谢谢！

你需要搬家

this._createGrid(stories);

在循环之外：

 _onDataLoaded: function(store, data){
                var stories = [];
                Ext.Array.each(data, function(story) {
                            var s  = {
                                FormattedID: story.get('FormattedID'),
                                Name: story.get('Name'),
                            };
                            stories.push(s);
                }, this);
                this._createGrid(stories);
    },
