I need to have a ref for a toolbar text component :

in the controller :

{ ref: 'toolYear', selector: 'creditgrid tbtext[id=year]'}

int the view :

dockedItems: [{
  xtype: 'toolbar',
  dock: 'top',
  items: [
    { xtype: '开发者_StackOverflow社区button', action: 'previous', iconCls: 'item-previous' },
    { xtype: 'tbtext', id: 'year' },
    { xtype: 'button', action: 'next', iconCls: 'item-next' },
  ]
}]

---

The issue was { ref: 'myRef', selector: 'myWidget #myid' }
