Presumably you would want such a construct to work regardless of what path a user took to get to a specific page (assuming there ARE multiple paths in your app, maybe there aren't). So, if it was me, I'd be thinking a linked list stored in session. Each page that is presented would append itself to the list. Clicking a link would have to break the list at the point of the page that was clicked (i.e., if there are six pages in the nav trail and the user clicks the third, you basically want to discard the last three, which just means removing the link to the next element from the element of the page the user clicked). You would of course have to add enough information to each element in the list as to allow your app to go to that page when clicked. Might just be storing the Action path, might mean each element is really a HashMap with a bunch of information, you would have to decide.
I'm not sure something like this exists yet, I'd certainly think it does though. If you have to roll your own, I suspect it wouldn't be too difficult using this approach (assuming I haven't glossed over something that makes it impossible or overly difficult of course!) -- Frank W.
