JavaFX - 처리기 메서드에 액세스 할 수 없습니다.

Question

JavaFX FXML 응용 프로그램에 약간의 문제가 있습니다. 문제는 #handleButtonAction 때문입니다. 어떤 이유로 Handler 메소드에 액세스 할 수 없습니다. 어제는 완전히 괜찮 았어. 지금이게 뭐가 잘못 됐는지 모르겠다. 어떤 아이디어? 현재 전체 응용 프로그램을 확인할 수 있습니다 GitHub

핸들러 방법은 컨트롤러 클래스가없는 둘 public도 있기 때문에 오류 메시지 상태, 접근 할 수없는 등 @FXML 주석. 특수 효과 추가 :

@FXML 
private void handleButtonAction(ActionEvent event) { 

    genNum1 = 0; 
    genNum2 = 0; 
    genNum3 = 0; 
    genNum4 = 0; 
    genNum5 = 0; 

    genNum1 = getRandomNumber(); 
    genNum2 = getRandomNumber(); 
    genNum3 = getRandomNumber(); 
    genNum4 = getRandomNumber(); 
    genNum5 = getRandomNumber(); 

    label1.setText(String.valueOf(genNum1)); 
    label2.setText(String.valueOf(genNum2)); 
    label3.setText(String.valueOf(genNum3)); 
    label4.setText(String.valueOf(genNum4)); 
    label5.setText(String.valueOf(genNum5)); 

    calculate(); 
}
