Martin Grigorov commented on WICKET-5958:
-----------------------------------------
I have troubles understanding the problem here.
If someone else understands the problem please explain it (or fix it).
IMO this is "Not a problem".
> PageNumberEvictionStrategy(1) crashes application if using ajax callback
> behaviours in Pages....

> Key: WICKET-5958
> URL: https://issues.apache.org/jira/browse/WICKET-5958
> Project: Wicket
> Issue Type: Bug
> Components: wicket
> Affects Versions: 6.20.0
> Environment: All operation systems.
> Reporter: Tomas Kloucek
> Attachments: myproject.zip
>
>
> As I promised in
> http://apache-wicket.1842946.n4.nabble.com/Howto-have-just-currently-viewed-page-in-session-td4671631.html
> , here is the promised demo.
> You've got there two pages, HomePage and RedirectPage, both with Ajax timer.
> First page is with redirect link. If you press that redirect link you're
> redirected to RedirectPage page, but that page is recreated without
> pageparameters eventually and application crashes with:
> Caused by: java.lang.IllegalArgumentException: Page parameters cannot be
> empty!
> at com.mycompany.myproject.RedirectedPage.<init>(RedirectedPage.java:26)
> If I look at PageProvider class and resolvedPageInstance method, it's clear
> why it crashes....
> But guys, as a page store developer, I want to have just currently viewed
> page in session, nothing more! When redirecting I don't care about previous
> page ajax callbacks...
> This bug is critical for us, so please do not lower the priority and please
> help us with it.
> Btw, yes, raising number of saved pages solves the problem, but this is not
> preferred solution for us, because we support multiple opened browser
> tabs.,,And it's causing me problems in page management...
> Looking forward for solution or at least tips...
