retriving the actual page instance
Hi, is there a way to get the actual IRequestablePage? I have only one, and
if I debug the HttpSession, I have this key:
"wicket:wicket.wicketGuide:wicket:persistentPageManagerData" which holds
the PageStoreManager$SessionEntry, where is the actual page I'm looking for.
I don't want to access in that way (navigating throw the raw httpSession).
I think there should be a better way using Wicket classes. Does anybody
know? thanks!

Thanks to both. Alec approach worked for me in other case, not in this one.
In this case, we had the problem that StaleException was rising, when user
open multiple tabs with the same session (like Firefox)
In that case, I was invalidating the whole session and redirecting to
login. But now, the user stays in the same page (with the last state) using
Session.get().getPageManager().getPage( id )
So now, the user can have multiple tabs and works fine. Thanks to both
Martin and Alec!

Re: retriving the actual page instance

I used this approach
https://cwiki.apache.org/WICKET/requestcycle-in-wicket-15.html to
retrieve the last page instance from request cycle.
1. Register handler in your Application:
getRequestCycleListeners().add(new PageRequestHandlerTracker());
2. Retrieve page as follows:
IPageRequestHandler lastHandler =
PageRequestHandlerTracker.getLastHandler(RequestCycle.get());
IRequestablePage page = lastHandler == null ? null : lastHandler.getPage();
Hope this helps,
Alec

Why do you need this functionality ?

Martin, thank you again!
This helps me a lot! what I dislike is that I need to know the page id, is
there a way to know the "last" page id? by now.. I'll put this id in the
session

Hi,
The official way is: session.getPageManager().getPage(pageId)
This will look in the httpsession and fallback to disk.
