Estou executando um programa simples em JavaFX que carrega os elementos de uma ComboBox, na primeira vez que executei ele rodou, porém os elementos da ComboBox não carregaram.
Percebi que eu tinha duas classes main, uma para o ComboBox outra default e resolvi deletar a default e deixar apenas a MainComboBox porém ao executar no NetBeans foi exibido o seguinte erro:
