KEYBOARD_DECIMAL_PAD and KEYBOARD_NUMBER_PAD open default keyboard

Hi all, recently I've found that bug:

amount =  Ti.UI.createTextField({
       hintText: L('total', 'Total'),
       keyboardType: Ti.UI.KEYBOARD_DECIMAL_PAD
});

on amount field focus I expect a decimal keyboard opened... But I get a standard keyboard and amount field lost focus... on selecting the field again I obtain the right keyboard.

I think it's a recent bug because it stop working some weeks ago...

Someone has the same issue and the solution?
