WicketInAction: question concernant navigtor
Bonjour à tous,
J'ai découvert Wicket il y a peu (quelques jours) et j'essaie de m'y former via le livre "Wicket In Action". Pour ceux qui possède le livre, je suis à la page 65.
Ma question (même si vous n'avez pas le livre, vous pouvez m'aider):
J'ai une liste de differents éléments à afficher et il conseille de passer par un "navigator" (càd montrer PAGE1, PAGE2,....).
J'ai suivi le tuto, mais cela ne fonctionne pas.

<a wicket:id="add" href="#">add to cart</a>

<div wicket:id="navigator"></div>
