Ralf Ebert commented on WICKET-2327:
------------------------------------
yes, explicitly setting setStatelessHint(false) yields correct urls.
Seems to be "the page tells that it is stateless/bookmarkable to easy" indeed -
I guess a page should be stateful by default till the developer explicitly
states that it is not.
Maybe one even should get an exception if you try to create an listener url for
a stateless page, because that's per definition not stateless...

> Key: WICKET-2327
> URL: https://issues.apache.org/jira/browse/WICKET-2327
> Project: Wicket
> Issue Type: Bug
> Components: wicket
> Affects Versions: 1.4-RC4
> Reporter: Ralf Ebert
> Fix For: 1.4-RC6

> When a component on a bookmarkable page uses urlFor to generate a URL to
> receive events, such an url is generated:
> http://localhost:8080/?wicket:bookmarkablePage=:somepkg.SomePage&wicket:interface=:12:bla::ISomeEventListener::
> If the given page expires and the URL is opened, Wicket tries to create a new
> page instead of throwing a PageExpiredException. This is incorrect in my
> opinion, because the URLs intention is to call a listener interface. In my
> understanding this cannot happen after the state of the page is lost, so a
> PageExpiredException should be thrown in this case (or a "non-bookmarkable"
> URL should be generated).
