Since the onchange event is broken for lookup widgets in Salesforce, has anyone come up with a suitable workaround? The thing seems to have been broken for at least 3 releases, which simply boggles the mind.
My desired use is to have the change detected so when a field is selected by the user, I populate another list or related objects for her to choose from. Right now i'm trying to fake this behavior with onblur, but I am not loving the results.
