Hi all, i tried to set up the helper method "grouped_programs_selector" in application_helpers.rb. Since i dont have a deep understanding of Ruby itself, I pretty much copied the Grouped Selection List (Chapter 17, pp. 259, 260) example from Dave & David''s Book. The optiongroups are properly created by my method, but there are no options inside. Maybe you can debug this
