MVC Sencha Touch Won't Properly Display Tab Panels

I have a MVC Sencha Touch application I'm building and am having some issues getting the TabPanel to function correctly. The issue is this, when I have my PosViewport.js like this, everything works fine:

touch.views.PosViewport = new Ext.extend(Ext.TabPanel, {
initComponent: function () {
    console.log("inside initComponent() of PosViewport.js");
    touch.views.PosViewport.superclass.initComponent.call(this);
},
tabBar: {
    dock: 'bottom',
    layout: {
        pack: 'center'
    }
},
layout: 'fit',
scroll: 'vertical',
items: [
    {
        title: 'Reciepts',
        iconCls: 'bookmarks',
        html: 'one'
    },
    {
        title: 'POS',
        iconCls: 'Favorites',
        html: 'two'
    }
]
});

Here, everything is great! The tab bar shows up on the bottom, it fits perfectly, and I can switch back and forth between the two with no problems.

However, instead of keeping those panels inside my PosViewport.js file, let's move them out to two seperate files:

View1.js:

touch.views.View1 = new Ext.extend(Ext.Panel, {
initComponent: function () {
    touch.views.View1.superclass.initComponent.call(this);
},
layout: 'fit',
scroll: 'vertical',
fullscreen : true,
title: 'Reciepts',
iconCls: 'bookmarks',
html: 'panel one'
});

and View2.js:

touch.views.View2 = new Ext.extend(Ext.Panel, {
initComponent: function () {
    touch.views.View2.superclass.initComponent.call(this);
},
layout: 'fit',
scroll: 'vertical',
fullscreen : true,
title: '2',
iconCls: 'bookmarks',
html: 'panel two'
});

I add both new views to my index.html. Now, I update my PosViewport.js to point to the new views:

touch.views.PosViewport = new Ext.extend(Ext.TabPanel, {
initComponent: function () {
    console.log("inside initComponent() of PosViewport.js");
    touch.views.PosViewport.superclass.initComponent.call(this);
},
tabBar: {
    dock: 'bottom',
    layout: {
        pack: 'center'
    }
},
layout: 'fit',
scroll: 'vertical',
items: [ touch.views.View1, touch.views.View2]
});

And it all goes to hell. The Bottom Tab Bar is not visible, as only a tiny piece of the top is visible on the page. The panels do not show up at all, I cannot see their HTML content at all.

What is going on here? I have absolutely no idea why it is behaving like this. Any pointers in the right direction are much appreciated, thank you!

In the second case you created two classes by this:

touch.views.View2 = new Ext.extend(Ext.Panel, {          // Class definition

whereas you needed two instances of these panels. So, add the items like this:

items: [new touch.views.View1(), new touch.views.View2()]   // Panel instance

This should work now. And remove the fullscreen:true option from these panels. fullscreen means, it will make the panels take whole viewport area.
