Sencha Touch 2.x - How to load a custom view into a tab panel? Use xtype?

Question

I am completely new to Sencha 2 Touch. This is my second day playing with it.

I have a custom class (app/view/Howdy.js):

Ext.define('MyApp.view.Howdy', {
  extend: 'Ext.Panel',
  xtype: 'howdy', // <--- this creates the 'howdy' xtype reference right?
  requires: [
    'Ext.SegmentedButton'
  ],

  config: {
    fullscreen: true,
    html: ['Hello Word.'].join("")  
  }
});

and I am now trying to load it into a tab when clicked:

Ext.define('MyApp.view.Main', {
   extend: 'Ext.tab.Panel',

   config: {
     fullscreen: true,
     tabBarPosition: 'bottom',

     items: [
        {
            title: 'TAB 1',
            iconCls: 'star',
            xtype: 'howdy', // <--- WHY IS THIS CRASHING MY APP?
        },
    ]
}
});

If I remove the xtype declaration inside TAB 1 and replace it with an html everything works fine. As soon as I try and load my custom view into the tab all I get is a white screen in my browser and console shows no errors ???

P.S Yes everything is setup correctly already in App.js:

views: ['Howdy','Main'],

HELP PLEASE!

Answer 1

Late to update this thread but the solution was simply to remove the fullscreen: true declaration from inside the config in MyApp.view.Howdy.

Answer 2

I hope that this will help you:

MyApp.view.Howdy

Ext.define('MyApp.view.Howdy', {
  extend: 'Ext.Container',
  xtype: 'howdy',
  requires: [
    'Ext.SegmentedButton'
  ],

  config: {
    incoCls: 'star',
    title: 'TAB 1',

    html: ['Hello Word.'].join("")  
  }
});

MyApp.view.Main

Ext.define('MyApp.view.Main', {
   extend: 'Ext.tab.Panel',

   config: {
     fullscreen: true,
     tabBarPosition: 'bottom',

     items: [
        {xclass: 'MyApp.view.Howdy'},
    ]
}
});
