JavaFX EventAction sorunu

merhabalar,
javaxf'e yeni başladım sayılır. buttonlara fx:id ile id'leri atıyorum. onAction="#event" şeklinde event da ekledim. bu fxml in controller class'ında

@FXML    private void kapat(javafx.event.ActionEvent event)
    {
        labelDurum.setText("asd");
    }

şeklinde event ekledim derlediğimde

Java Result: 1
jfxsa-run:
BUILD SUCCESSFUL (total time: 9 seconds)

şeklinde bir çıktı oluşuyor ve "exception while runnig application" diye uyarı verip program kapanıyor.

sorunu nasıl çözebilirim ? bir de javafx komponentlerine event eklememin daha basit bir yolu var mı ?

not: javafx'in kendi tuturial'deki kodların aynısını kullandım işe yaramadı.

edit:sorunu çözdüm. fxml dosyasında ana parent'a fx:controller tanımlamamışım :)
