Adding buttons in Sencha Touch

I want to update the toolbar's content of the main view from a subview (HotelApp.views.hotelDetail)

This is my toolbar from HotelApp.views.mainView

    this.topBar = new Ext.Toolbar({
        dock:'top',
                    id:'main_page_topbar',
        title:'H10 Sencha Demo',
                    items:[this.back,
                           {xtype: 'spacer'}
                    ]
    });

The toolbar already have a back button. The problem is i can see the shape of a button, but no text either ID. What i'm doing wrong??

I use this code:

var toolbar = HotelApp.views.mainView.getDockedItems()[1];

var images = new Ext.Button({
                 text:'Images',
                 id:'images',
                 ui:'drastic'
 })

too开发者_如何学Pythonlbar.setTitle(record.get('nombre'));
toolbar.add({items: images});
toolbar.doLayout();

Thanks!!!

I think that your problem is only that you have to add your button calling

toolbar.add(images);

instead of

toolbar.add({items: images});

I even suggest you to don't use 'id' config for your components but 'itemId'. In this way you can always get your views components by calling

myView.getComponent('myComponentItemId');

or

myView.getDockedComponent('myComponentItemId');

for DockedComponents like toolbars. Hope this helps.
