Witam,
Próbuję zrobić formularz, w którym z bazy będę mógł wybrać film i kino z dropdownlist. Napisałem dropdowna, ale wyświetlają się w nim dodatkowe rzeczy, mimo że przesłoniłem metodę toString(). Jak to zrobić, aby można było wybrać film i kino, a następnie prawidłowo zapisać do bazy encje Showing.
Encje:
