Answer 1

I finally rewrote the code so that I didn't have var view = Ext.create('.... instead I had Ext.define('... then I added:

 `var owningNavView = list.up('main'); 
  owningNavView.push({
  xtype : 'barFoo...'  });`

For sliding to the next card.

After that everything ran well with no errors.
