Uncaught Error: Ext.setup has already been called before

[Ades]

Hallo i have a program, which has a Login Panel and after the Login it has to show me another View. I would like to switch after login to the Ext.ux.touch.grid.
https://github.com/mitchellsimoens/Ext.ux.touch.grid

i have a LoginView. a Controller which looks like:

Ext.define("Login.controller.MainController",{
extend:'Ext.app.Controller',

views:['LoginView', 'HauptSeite', 'index'],



//--------------------------------------------------------refs, control
refs:[{ loginSeite :'#loginForm'}],

init: function(){
console.log('inited');

this.control({
'button[action=submitkontakt]': {
tap:'submitkontaktForm'
}
});
},


//--------------------------------------------------------refs, control






//definition von "submitgridForm"


submitkontaktForm:function(btn){
var form=btn.up('formpanel');

//console.log(form);
form.submit({
url:'login.php',

success : function(form, res){
console.log('right');
Ext.Viewport.setActiveItem(Ext.create('LoginAufGrid.view.index'));


alert('You are logged in');
},

failure : function(form, res){

console.log('false');
alert('wrong Login');
}
})
},


});

this part: Ext.Viewport.setActiveItem(Ext.create('LoginAufGrid.view.index')); should give a new View of Ext.ux.touch.grid.

I try to change the index.js of Ext.ux.touch.grid, so maybe it can work, but i can't find a solution.
I get allways the Error: Uncaught Error: Ext.setup has already been called before.

How can i change the part of :

Ext.setup({
onReady:function(){

Please help me
Thanks

ok i have the solution :-)

I copy the content from index.js of : https://github.com/mitchellsimoens/Ext.ux.touch.grid

but i changed the index.js bevor, therefore it looks different.

i copy my index.js in a class => Page2.js and there ist now:

Ext.define("Login.view.Page2", {
extend: 'Ext.Container',

initialize:function(){
Ext.define('TestModel', {
extend : 'Ext.data.Model',


config : {
fields : [
'name',
'zahl',
'einzugstermin'
]
}
});


var store = Ext.create('Ext.data.Store', {
model : 'TestModel',
autoLoad : true,
data : [
{ name : 'b', zahl : 71.72, einzugstermin : '9/1/2010' },
{ name : 'a', zahl : 72.72, einzugstermin : '9/1/2010' },
{ name : 'r', zahl : 73.72, einzugstermin : '9/1/2010' },
{ name : 'd', zahl : 70.72, einzugstermin : '9/1/2010' }
]
});


var grid = Ext.create('Ext.ux.touch.grid.List', {

height : 300,

store : store,


features : [
{
ftype : 'Ext.ux.touch.grid.feature.Sorter',
launchFn : 'initialize'
}
],


columns : [
{
header : 'Name',
dataIndex : 'name',
style : 'padding-left: 1em;',
width : '40%',
filter : { type : 'string' }
},
{
header : 'Zahl',
dataIndex : 'zahl',
style : 'text-align: center;',
width : '15%',
filter : { type : 'numeric' }
},
{
header : 'Einzugstermin',
dataIndex : 'einzugstermin',
cls : 'centered-cell redgreen-cell',
width : '15%',
renderer : function (value) {
var cls = (value > 0) ? 'green' : 'red';


return '<span class="' + cls + '">' + value + '</span>';
}
}
]


});

this.add( grid);

store.load();
}
});

and in the Controller i can call it with => Ext.Viewport.setActiveItem(Ext.create('Login.view.Page2'));

submitkontaktForm:function(btn){
var form=btn.up('formpanel');

//console.log(form);
form.submit({
url:'login.php',

success : function(form, res){
console.log('right');
Ext.Viewport.setActiveItem(Ext.create('Login.view.Page2'));


alert('You are logged in');
},

failure : function(form, res){

console.log('false');
alert('wrong Login');
}
})
},

and it works :-)
