I am currently doing the Griffon tutorial MVC Groups (JavaFX). I dont get this running because I cant compile griffon-app/i18n/messages.properties. It says:
Caused by: griffon.core.editors.ValueConversionException: Can't convert 'org.kordamp.ikonli.javafx.FontIcon|fa-power-off' into javafx.scene.Node
If I comment out this lines, it compiles and runs but of course it shows not icons. How do I get icons into the file menu with Griffon?
