OK, thanks for the info Igor. I guess the idea is that Pages themselves are considered to be disposable (unless a reference is passed around) and if their "state" is important, any underlying model(s) should be maintained by the app and used to set the Page's components' model state, as appropriate, when the page is revisited. It just seems a bit unintuitive that a new instance of the Page is created by default (if the reference to the original instance is not passed around) even though there is possibly an instance/instances already sitting in the PageMap, just waiting to be evicted - I expect there is some stuff going on to encourage this Wicket design decision that I haven't totally appreciated yet.
