Is autoCreateViewport not working as intedned?

[darren]

Hey all, temporarily I am using:

Ext.application({
    name: 'Advertiser',
    appFolder: '/js/Portal/Advertiser',
    launch: function () {
        Ext.create('Portal.Advertiser.view.Viewport');
    }
});

But I would like to use:

Ext.application({
    name: 'Advertiser',
    appFolder: '/js/Portal/Advertiser',
    autoCreateViewport: true
});

However nothing loads when trying to use autoCreateViewport. When I do the explicit create it loads.

Here is my viewport:

Ext.define('Portal.Advertiser.view.Viewport', {
    extend: 'Ext.container.Viewport',
    layout: 'border',
    initComponent: function () {
        this.items = [{
            xtype: 'container',
            region: 'north',
            height: 100
        }, {
            xtype: 'container',
            region: 'west',
            width: 200,
            items: [{
                xtype: 'panel',
                html: 'Menu'
            }]
        }, {
            xtype: 'tabpanel',
            region: 'center',
            activeTab: 0,
            items: [{
                xtype: 'panel',
                title: 'Dashboard',
                html: 'Coming soon'
            }]
        }];


        this.callParent();
    }
});

Can someone perhaps give me guidance on what I am doing wrong or is this a possible bug?

Thanks

Perhaps try adding 'views'/requires property to application({}) to use autoCreateViewport?
I believe that it is recommended to create then yourself anyway instead using autoCreateViewport. It was already removed from Touch2, Ext4 may follow, but I that is just a guess at this point.
