Bonjour,
j'ai essayé de pratiquer l'exemple "IssueTrackingLite.zip" du tutoriel qui se trouve à: http://docs.oracle.com/javafx/sceneb...et_started.htm
en utilisant NetBeans 8 et JavaFX Scene Builder 2.0, j'ai réussi à appliquer l’exemple à la lettre mais malheureusement je n'arrive pas à l'exécuter. voici l’erreur généré par lIDE:
