Assuming the class diagram at http://jweekend.com/dev/ArticlesPage/ is up-to-date for your version of Wicket, perhaps you can override "protected ITreeState newTreeState()" to return an ITreeState that you pass between pages (or, put in your custom WebSession if that makes more sense in your app or in a table or ....). I wouldn't be surprised if Matej comes back to say there's a neater way than that!
