[Spiritkill]

Bonjour,

Je suis en train de développer un application swing.
J'utilise Hibernate et et le binding.

Mon projet:
J'ai 2 Entity Class : Exercise et Evolution.
un Exercise a un liste d'évolution.

Au niveau de l'interface, un JTree qui représente mes exercices et une JList permet d'afficher les évolutions de l'exercice selectionné par binding.
Un bouton permet aussi de rajouter une évolution à l'exercice selectionné.

Je voudrait savoir, comment l'ajout d'un évolution à un exercise peut se faire pour que la JList se raffraichisse.

Merci pour votre aide.
