继续我的应用程序，其目的是能够编辑聚合字段并将计算结果存储在该聚合的各个组件中...
我现在可以使用UserStory模型的扩展来正确检索我的字段，但我仍然无法保存我的更改。 我试图检查在Ext.grid.plugin.RowEditing的编辑事件中做了什么，我注意到当我到达它时，e.store.data.items [rowIdx] .data包含我所有的期望值，它的脏和编辑标志是假的，但是e.store.data.items [rowIdx] .raw没有反映出来（它包含Rally的原始值，未经修改） - 即使我尝试编辑raw中的值，它也不起作用：
plugins: [
Ext.create('Ext.grid.plugin.RowEditing', {
clicksToEdit: 1,
listeners: {
'edit': function (editor, e) {
e.store.data.items[e.rowIdx].raw.BusinessValues =
e.store.data.items[e.rowIdx].data.BusinessValues;
e.store.commitChanges();
}
}
})
]
整个代码如下，但我想知道是否应该在模型级别添加一个监听器？
Rally.onReady(function() {
Ext.define('BVApp', {
extend: 'Rally.app.App',
componentCls: 'app',
launch: function() {
Rally.data.ModelFactory.getModel({

success: function(model) {
var weights = new Array(5, 3, 1, 3, 4, 4, 2, 2);
var BvTitles = new Array("Customers Impact", "Critical Path", "Usability", "Functionality", "Security", "Performance", "Integration", "Integrity", "Business Value");
//var BvTitlesFrench = new Array("Parc Client", "Chemin Critique", "Ergonomie", "Fonctionnalité", "Sécurité", "Performance", "Intégration", "Intégrité", "Valeur Métier");

我的建议是使用get＆amp;设置记录对象的功能以检索和更改数据，而不是挖掘“数据”或“原始”字段。这样，Ext库可以更好地管理更改以正确更新存储/记录。
因此，当您想获取“BusinessValues”字段的值时，请使用record.get('BusinessValues')。同样，尝试record.set('BusinessValues', newValue)在getOneBV函数中设置新值。在执行此操作时，您可以注释掉您添加的RowEditing插件。
