Extjs6.2隐式TypeError: touchScrollable.getElement不是一个函数

Question

以前有人见过这个错误吗？我们将应用程序升级到extjs6.2，当我通过平板(从chrome的开发工具)打开它时，我会看到下面的错误。

Main.js码

    Ext.define('eProject.view.desktop.viewport.Main', {
    extend: 'Ext.panel.Panel',
    requires: [
        'eProject.view.desktop.login.Main',
        'eProject.view.desktop.main.Main'
    ],
    xtype: 'app-desktop-viewport',
    layout: 'card',
    items: [
        {
            xtype: 'panel',
            layout: 'center',
            items: [
                {
                    xtype: 'label',
                    text: 'Loading ...'
                }
            ]
        },
        {
            xtype: 'app-desktop-login'
        },
        {
            xtype: 'app-desktop-main'
        }
    ],
    listeners: {
        beforerender: function (panel) {
            eProject.util.Localizer.update(panel, true);
        }
    },
    localizerUpdate: function () {
        eProject.util.Localizer.update(this, false);
    },
    setLoggedIn: function (status) {
        if (status && status == true)
        {
            this.setActiveItem(2);
        }
        else
        {            
            this.setActiveItem(1);
            this.down('app-desktop-login').resetInput();
        }
    }
});

控制台错误中显示的行是this.setActiveItem(2);。

更新1

在某些情况下，从面板中删除resizable: true可以解决这个问题。

更新2

这有点奇怪，但是从所有的网格面板(和一棵树)中删除resizable: true解决了这个问题。

Answer 1

显然，将项目升级到extjs6.2.1解决了这个问题。
