I've added some custom fields to a user form using the technique described here:
http://rtfm.modx.com/revolution/2.x/case-studies-and-tutorials/adding-custom-fields-to-manager-forms. The "Save" button remains grayed out when the custom fields change.
I assume that I can throw in a bunch of "OnChange()" functions, but is there an easier way to make changing them light up the "Save" button?
