Is there a known bug with observe_field using the :on parameter?
I want to observe a select list, and only update a child select list
after someone has made a selection, so I want to use the onSelect
event. However no matter what I set as the value of :on it still
behaves as if it is set to change (the default).
I came across this http://joshhuckabee.com/taxonomy/term/5 which
implies there is a bug - I even change my prototype.js to match his
changes, but it still is not behaving as I would have expected.
I have used onSelect before in select lists, and it definitely only
fires when you actually make the selection, so I am very confused!
