HTML_QuickForm_element::freeze() -- Freezes the element
Descripción
When the element is displayed after the call to freeze(), only its value is displayed without the input tags, thus the element cannot be edited. If persistant freeze is set, then hidden field containing the element value will be output, too.
Nota:
This method makes sense only with the elements that actually are editable in the
first place. It has no effect on buttons, images, hidden fields, static content
and the like.
Lanza

Esta función no puede ser llamada
