dhtmlx combo, need firefox problem

The field should have this attribute applied to it if we have auto complete on:


The problem is firefox automatically tries to auto complete the field based on previously entered values, which is a popup that covers the dhtmlx results box that pops up with autocomplete values.

How can I add this?

dhtmlxcombo.js , line 1119

dhtmlXCombo_defaultOption.prototype._DrawHeaderInput = function(self, name, width,tab)
   var z=document.createElement(‘input’);
   z.className = ‘dhx_combo_input’;
    z.setAttribute(“autocomplete”,“off”); // <<< can be added
   z.type = ‘text’;

We will add similar fix for next version, thanks for recomendation.
