I'm an idiot : )
This error has nothing to do with the form, but is due to the way
`stopObserving` works. We had this "issue" fixed in a trunk but then
it was temporarily removed before 1.6.0.3 release. The problem is that
`stopObserving` accepts optional 2nd and 3rd arguments and when passed
as an iterator (to `each`) it gets called with `value` and `index`
arguments that are being passed to an iterator.
You can use `invoke` meanwhile (don't forget to extend an element
first and then return it from the method):
Element.addMethods({
stopObservingNested: function(element) {
element = $(element);
element.descendants().invoke('stopObserving');
return element.stopObserving();
}
});
