    Default Ext.ux.Ajax

    Here we go guys with a new extension!

    Ext.ux.Ajax seems to replace the old Ext.Ajax, indeed.
    Well, that's correct :P

    Ext.Ajax is just a singleton of Ext.data.Connection, while Ext.ux.Ajax is a singleton that uses Ext.data.Connection and Ext.ux.Deferred!
    And now, here I am to show you how Ext.ux.Ajax works

    Problem:

    Code:
    Ext.Ajax.request ({
        url: 'data.json' ,
        success: function (data) {
            Ext.Ajax.request ({
                url: 'data2.json' ,
                success: function (data2) {
                    Ext.Ajax.request ({
                        url: 'data3.json' ,
                        success: function (data3) {
                            alert ("It's so hard to reach the top!");
                        } ,
                        failure: errorHandler
                    });
                } ,
                failure: errorHandler
            });
        } ,
        failure: errorHandler
    });
    How Ext.ux.Ajax solves this problem:

    Code:
    Ext.ux.Ajax
        .request ('data.json')
        .then (Ext.ux.Ajax.request ('data2.json'), errorHandler)
        .then (Ext.ux.Ajax.request ('data3.json'), errorHandler)
        .then (function (data3) {
            alert ("Ah! That's much better ;)");
        }, errorHandler);
    There's no magic behind this extension: in the request method, the AJAX request is wrapped into a promise (Ext.ux.Deferred instance) and it is returned, making the class chainable.
