Hello

Is it possible to use JSON as the data format in a Ext.List ?

Example from http://docs.sencha.com/touch/1-1/#!/api/Ext.List
Code:
Ext.regModel('Contact', {
    fields: ['firstName', 'lastName']
});

var store = new Ext.data.JsonStore({    model  : 'Contact',
    sorters: 'lastName',

    getGroupString : function(record) {
        return record.get('lastName')[0];
    },

    data: [
        {firstName: 'Tommy',   lastName: 'Maintz'},
        {firstName: 'Rob',     lastName: 'Dougan'},
        {firstName: 'Ed',      lastName: 'Spencer'},
        {firstName: 'Jamie',   lastName: 'Avins'},
        {firstName: 'Aaron',   lastName: 'Conran'},
        {firstName: 'Dave',    lastName: 'Kaneda'},
        {firstName: 'Michael', lastName: 'Mullany'},
        {firstName: 'Abraham', lastName: 'Elias'},
        {firstName: 'Jay',     lastName: 'Robinson'}
    ]
});

var list = new Ext.List({
    fullscreen: true,
    
    itemTpl : '{firstName} {lastName}',
    grouped : true,
    indexBar: true,
    
    store: store
});
list.show();
So something like this instead:

Code:
Ext.regModel("Contact", {
    fields: ["firstName", "lastName"]
});
var store = new Ext.data.JsonStore({
    model  : "Contact",
    sorters: "lastName",
    getGroupString : function(record) {
        return record.get("lastName")[0];
    },
    data: [
        {"firstName": "Tommy",   "lastName": "Maintz"},
        {"firstName": "Rob",     "lastName": "Dougan"},
        {"firstName": "Ed",      "lastName": "Spencer"},
        {"firstName": "Jamie",   "lastName": "Avins"},
        {"firstName": "Aaron",   "lastName": "Conran"},
        {"firstName": "Dave",    "lastName": "Kaneda"},
        {"firstName": "Michael", "lastName": "Mullany"},
        {"firstName": "Abraham", "lastName": "Elias"},
        {"firstName": "Jay",     "lastName": "Robinson"}
    ]
});
var list = new Ext.List({
    fullscreen: true,
    
    itemTpl : "{firstName} {lastName}",
    grouped : true,
    indexBar: true,
    
    store: store
});
list.show();
Any suggestions are very welcome.
