focusFirstElement() fails on empty forms

Reported by achernin | September 15th, 2008 @ 08:57 AM | in 1.7

prototype.js, Version: '', Line 3462

focusFirstElement: function(form) {

form = $(form);
return form;


this code is unsafe. findFirstElement() function returns empty value, if form has no elements.

proposed solution is

focusFirstElement: function(form) {

form = $(form);
var element = form.findFirstElement();
element && element.activate();
return form;
