Question

我已通过此sample创建了一个面板，它在tools配置下有2个项目。这两个项目都有自己的功能，通过ViewController绑定。 refresh项的功能运行良好，但gear项的功能在下面给出了这个错误;

Uncaught TypeError: Cannot read property 'scope' of undefined

    at constructor (Observable.js?_dc=1516015518102:403)

我已将视图类从app文件夹移动到classic文件夹，但ViewController类保留在app文件夹中，所以我猜错误是通过{{ 1}}符号。我应该如何在ViewController中声明它？

更新我为视图创建了weatherWindow: function () { var win = this.lookupReference('weatherWindow'); if (!win) { win = new MyApp.view.weather.SettingsWindow(); this.getView().add(win); } win.show(); },但仍然出现ViewController错误！

scope

我找到了解决此错误的方法。在窗口类中创建了一个函数并返回它;

getSettingsItems: function () {
    var me = this;

    var settingsItems = [
        // whole items listed here!
    ];

    return settingsItems;
},
