[2.1] Overriding singleton not working

[Steffen Hiller]

I'm getting the same error as in this bug report from March which was reported as fixed:
http://www.sencha.com/forum/showthread.php?185360

Error:
Uncaught TypeError: Object [object Object] has no method 'override'
File: sencha-touch.js:6597
Line: this.get(overriddenClassName).override(data);

Test case:

Ext.define('App.override.util.Format', {
    override: 'Ext.util.Format'
});

My work around for now:

Ext.define('App.override.util.Format', {
}, function () {
    var date_without_override = Ext.util.Format.date;
    
    Ext.util.Format.date = function (value, format) {
        ... // my override code
        
        return date_without_override(value, format);
    };
});

That post wasn't marked as fixed, it was closed due to this statement from Jamie:

Thank you for the report. You should be able to just directly change that singleton instance as a workaround until we resolve that.
