This application needs to be GUI tic tac toe, but when I click to button which only need to set all labels text to " " i get this message. I think that problem is with Event handler,but im not sure. It is my first ''biggest'' project with javaFX and I need help. If you need another code from project, tell me and i will upload. Thanks
