Switch views with button - sencha-touch-2

Question

I have two views. The User view has some text and a button. I want to use that button to switch to the second view. But i don't know how this works with sencha touch 2. When i press the button on the "UserView" (which is the first view), then i get the following error:
Uncaught Error: SYNTAX_ERR: DOM Exception 12
This is basically how my code looks right now:
app.js
Ext.Loader.setConfig({ enabled: true });
Ext.setup({
viewport: {
autoMaximize: false
},
onReady: function() {
var app = new Ext.Application({
name: 'AM',
controllers: [
'Main'
]
});
}
});
The Main controller
Ext.define('AM.controller.Main', {
extend: 'Ext.app.Controller',
views : ['User'],
init: function() {
this.getUserView().create();
this.control ({
'#new': {
tap: function() {
alert('aaaa');
}
}
});
}
});
And the two views:
Ext.define('AM.view.User', {
extend: 'Ext.Container',
config: {
fullscreen:true,
items: [{
xtype: 'button',
text: 'New',
id: 'new'
}
],
html: 'Testing<br />'
}
});
2nd view
Ext.define('AM.view.New', {
extend: 'Ext.Container',
config: {
fullscreen: true,
html: 'w00t'
}
});

Here is your application written the way it should be. Here are a few notes about the changes I made:
You should call Ext.application instead of Ext.setup when creating your MVC application.
All root views should be defined inside your app.js.
You no longer need to use this.control() in your controllers. You can simply use the control configuration in the config block.
You should define all views in the views config of Ext.application.
Instead of creating the view in init, do it in launch. This is components should be added into the view.
app/view/User.js
Ext.define('AM.view.User', {
extend: 'Ext.Container',
config: {
items: [
{
xtype: 'button',
text: 'New',
id: 'new'
}
],
html: 'Testing<br />'
}
});
app/view/New.js
Ext.define('AM.view.New', {
extend: 'Ext.Container',
config: {
html: 'w00t'
}
});
app/controller/Main.js
Ext.define('AM.controller.Main', {
extend: 'Ext.app.Controller',
config: {
control: {
'#new': {
// On the tap event, call onNewTap
tap: 'onNewTap'
}
}
},
launch: function() {
// When our controller is launched, create an instance of our User view and add it to the viewport
// which has a card layout
Ext.Viewport.add(Ext.create('AM.view.User'));
},
onNewTap: function() {
// When the user taps on the button, create a new reference of our New view, and set it as the active
// item of Ext.Viewport
Ext.Viewport.setActiveItem(Ext.create('AM.view.New'));
}
});
app.js
Ext.application({
name: 'AM',
// Include the only controller
controllers: ['Main'],
// Include all views
views: ['User', 'New'],
// Give the Ext.Viewport global instance a custom layout and animation
viewport: {
layout: {
type: 'card',
animation: {
type: 'slide',
direction: 'left',
duration: 300
}
}
}
});
I also suggest you checkout the great guides over on the Sencha Touch API Docs, as well as checking out the Sencha Forums as they are very active and are a great source of information.
