Wie öffne ich eine FXML-Datei im Szenen-Generator, nachdem ich ein nicht unterstütztes CheckComboBox-Steuerelement hinzugefügt habe?

Question

Ich entwickle eine JavaFX-Anwendung mit IntelliJ IDEA und Scene Builder. Um eine Combobox mit Mehrfachselektion zu erstellen, habe ich die controlsfx.jar-Bibliothek sowohl in den Szenengenerator als auch in mein Projekt importiert und plane, das von ihnen bereitgestellte CheckComboBox-Steuerelement zu verwenden, wie vorgeschlagen here.

Beim Importieren der Bibliothek in den Szenengenerator gehörte das CheckComboBox-Steuerelement nicht zu den geladenen Steuerelementen. Also habe ich die FXML-Datei bearbeitet und durch geschriebenen Code eingefügt.

Leider, nachdem ich dies getan habe kann ich nicht mehr die FXML-Datei im Szenen-Generator öffnen. Dieser Fehler tritt auf, wenn ich versuche, es von IntelliJ IDEA direkt zu öffnen:

Als ich die ersten Scene Builder ausführen und versuchen, die Datei von dort zu öffnen, bekomme ich diesen Fehler:

Obwohl ich habe Java Version 8 Update 91 ...

Ich würde wirklich gerne weiterhin mit Scene Builder arbeiten. Was könnte ich dagegen tun?

Vielen Dank!

Answer 1

Dank José Pereda wechselte ich zu another version of Scene Builder und mein Problem verschwand. Ich kann jetzt das CheckComboBox-Steuerelement mit Scene Builder verwenden.
