    Default Answered: ExtJs 4.0 Tutorial issues.

    Hello, I am trying to go through this tutorial:

    http://docs.sencha.com/ext-js/4-0/#!...n_architecture

    I am getting to the part where the view is supposed to become visible, however, instead I get an error in the console that says 'TypeError: name is undefined'.

    I believe all my code is correct, I have index.html with:

    Code:
    <html>
    <head>
        <title>Hello Ext</title>
    
        <link rel="stylesheet" type="text/css" href="ExtJs/ext-4.1.1a/resources/css/ext-all.css">
        <script type="text/javascript" src="ExtJs/ext-4.1.1a/ext-debug.js"></script>
        <script type="text/javascript" src="app.js"></script>
    </head>
    <body></body>
    </html>

    app.js

    Code:
    Ext.application({
        name: 'AM',
    
        appFolder: 'app',
        controllers: ['Users'],
    
        launch: function() {
            Ext.create('Ext.container.Viewport', {
                layout: 'fit',
                items: {
                    xtype: 'userList'
                }
            });
        }
    });
    app/controller/Users.js with

    Code:
    Ext.define('AM.controller.Users', {
        extend: 'Ext.app.Controller',
        views: [
            'user.List'],
    
        init: function() {
            this.control({
                'viewport > panel': {
                    render: this.onPanelRendered
                }
            });
        },
    
        onPanelRendered: function() {
            console.log('This panel was rendered');
        }
    });
    app/view/user/List.js

    Code:
    Ext.define('AM.view.user.List' ,{
        extend: 'Ext.grid.Panel',
        alias : 'widget.userlist',
    
        title : 'All Users',
    
        initComponent: function() {
            this.store = {
                fields: ['name', 'email'],
                data  : [
                    {name: 'Ed',    email: 'ed@sencha.com'},
                    {name: 'Tommy', email: 'tommy@sencha.com'}
                ]
            };
    
            this.columns = [
                {header: 'Name',  dataIndex: 'name',  flex: 1},
                {header: 'Email', dataIndex: 'email', flex: 1}
            ];
    
            this.callParent(arguments);
        }
    });

    Can anyone tell me what's wrong? Thank you.

  2. Instead of having views on the controller, try putting it on the application to see if it loads from there. The issue is the class is not being loaded.

    I was able to reslve the issue, it was due to the changing of capitalization of userList. I am not sure how to mark this as 'answered'.
