Schönen guten Tag,
ich stehe momentan auf dem Schlauch. Ich habe gerade ein neues Projekt angefangen, bekomme aber folgende Fehlermeldung:
Main.java
LoginController.java
Login.fxml
Die Anwendung lässt sich starten, sollte ich jedoch auf den Button drücken um das Fenster zu minimieren erhalte ich diese Fehlermeldung.
(Die CSS habe ich außen vorgelassen, sollte diese benötigt werden einfach schreiben (kann ich mir aber nicht vorstellen ^^))
Würde mich über eine Antwort freuen.
Gruß
