    Default help with Error: [Ext.createByAlias]

    this is my view main.js
    Code:
    Ext.define('App.view.Main', {    
        extend: 'Ext.Container',   
        xtype: 'mainview', 
        
        requires: [
            'App.view.NavigationPanel',
            'App.view.ContentPanel',
        ],
        
        config: {
            fullscreen: true,   
            layout: 'fit',
            items: [  
                {   
                    xtype: 'navigationpanel',
                    id: 'myNavigationPanel',
                },
                {   
                    xtype: 'contentpanel',
                    id: 'myContentPanel',
                },
            ]
        },                
    });
    this is my controller main.js
    Code:
    Ext.define('App.controller.Main', {
    extend: 'Ext.app.Controller',
    
    config: {
    profile: Ext.os.deviceType.toLowerCase() , 
    refs:{
    main:{
    selector : 'mainview',
    xtype : 'mainview',
    autoCreate: true,
    },
    },
    
    },
    views : [
    'Main',
    'MenuList',
    'EditarList',
    'NovaPastaPanel',

    Is the App.view.Main class in the Main.js file loaded?

    Use the dev tools. Type the class name in the console and if it's undefined the it hasn't been loaded. Check the network tab, has the file been loaded?

    I had the same problem with a panel after switching von B2/3 to RC1.

    After adding it into the views section in my application the error is gone.

    Code:
    Ext.application({
    ...
        views: [ 'my.view.component' ]
    ...
    });
