Robię projekt w JavieFX i mam problem, który polega na tym, że MainController nie otrzymuje zaaktualizowanej listy z AddControllera. Albo po prostu AddController nie zwraca prawidłowo listy i jsonObject. Zaimplementowałem przy dodawaniu obiektu do listy, żeby zamieniał obiekty na format json, aby zapisać je potem w pliku jako tekst. Prawidłowo dodaje obiekty do listy, bo pokazuje mi je w TableView i potem prawidłowo konwertuje obiekty na jsonObject, bo sprawdziłem w konsoli. Niestety, przy zapisie jsonObject jest pusty. Próbowałem to robić na kilka sposobów, ale już nie mam pomysłu. Może ktoś tutaj zauważy gdzie popełniam błąd.
