Wyrzuca NullPointerException

Tworzę obiekt

Movie movie = new Movie(textOriginalTitle.getText().trim(), textTitle.getText().trim(), textDirector.getText(), textScreenplay.getText(), (String)comboGenre.getSelectedItem(), (String)comboCountry.getSelectedItem(), comboDay.getSelectedItem() + "." + comboMonth.getSelectedItem() + "." + comboYear.getSelectedItem(),  numberOfMovies+1, runtime, budget, boxOffice, (int)comboRate.getSelectedItem(), commentRate.trim(), textOfficialSite.getText().trim(), textStudio.getText(), textDescription.getText().trim(), textTag.getText(), textOtherTitle.getText(), textFilmweb.getText().trim(), textIMDB.getText().trim(), path);

Och to proste. COŚ tam jest nullem. Ale że zrobiłeś to wszystko w 1 linijce to nie wiadomo co ;)

Niech każda z tych metod w konstruktorze wykonuje się do jakiegoś obiektu tymczasowego, którego później przekażesz do konstruktora. Łatwiej będziesz mógł zdebugować co tam jest null'em, bo tak to się nawet nie dowiesz :)

PS: W ogóle taki konstruktor to trochę maraska jest.

Stwórz sobie Builder do tego obiektu. Wtedy przynajmniej będziesz wstanie w przybliżeniu zlokalizować co może być nullem.

a poza tym
