First a patch is needed http://dev.rubyonrails.org/ticket/7396
That tenery operator wont work in that situation.... you need to evaluate
the return of the function
onUpdate : function (el) {
// do your code
}
revert : changeClass // function call
And you change class must provide a boolean true or false.....
function changeClass(el,o,n) {
return (Element.hasClassName( el, n.id)) ? true : false;
}
This should do the trick for you
