Question

i am wondering about the ‘refs’ attribute of Sencha Touch class ‘Ext.app.Controller’.
I saw a video tutorial where a simple contactForm was built. No i’ve tried to build a contact form for my app and i get an error: ‘Uncaught TypeError: Object [object Object] has no method ‘getContactForm”

Here’s my controller

Ext.define('MyFirstApp.controller.Main', {
extend: 'Ext.app.Controller', 
views: ['Viewport', 'Home'],

refs: [
     {
         ref: 'contactForm',
         selector: '#contactForm'
     }
],

init: function() {
    this.control({
        'button[action=submitContact]': {
            tap: 'submitContactForm'
        }
    });
},

submitContactForm: function() {
    var form = this.getContactForm();
    form.submit({
        url: 'contact.php'
    });
}

});

I guess it’s something wrong with the ‘refs’, in the video that guy said the “getContactForm” method will be created because of the “ref” attribute of “contactForm” but it doesn’t. What am i doing wrong here?..Thanks for help!

It looks as though you may have the refs configured wrong. Here’s a simple controller:

Ext.define('App.controller.Main', {
  extend: 'Ext.app.Controller',
  config: {
    refs: {
      main: 'mainpanel'
    }
  }
});

mainpanel is an xtype or could be a css selector and main will give you getMain() like what was talked about in the video.
