Got it, the widget is using Prototype 1.6.0 where the display function
IS defined :

  display: function(element, bShow) {
    if(bShow) { Element.show(element); } else
{ Element.hide(element); }
  },

but my Rails app is using Protoype 1.6.0.2 where this function IS NOT
defined, is it a bug or not  ??
