Hi Martin!
Sorry for confusion! I didn't mean stateless page, but unversioned one. I'll
give you an simplest example, it will do best:
PAGE 1:
public class WicketMainPage extends WebPage {
public WicketMainPage() {
PopupPage page = new PopupPage("Created: " + new Date());
// getSession().getPageManager().touchPage(page);
PageProvider pp = new PageProvider(page);
RenderPageRequestHandler rh = new RenderPageRequestHandler(pp);
add(new Label("url", urlFor(rh).toString()));
}
}
as you can see, I only create an instance of second page (which is not
bookmarkable as it has some parameters), wrap it in page provider and request
handler and simply output URL for it (of course it is an stateful URL).
The second page is just simple outputting text from constructor
PAGE 2:
public class PopupPage extends WebPage {
public PopupPage(String text) {
add(new Label("text", text));
}
}
When I run this, the app outputs an relative part of URL to the second page...
if I copy this into browser, everything works, when pages are versioned. But
when I set setVersionPagesByDefault(false) I start to get PageExpiredException
whe trying to access the second page. When I uncomment the touchPage line,
everythings works even with unversiones paged.
I tried to debug the code of Wicket and I noticed, then the page is touched
and thus stored in touched pages adn then in page map only when it is
versioned.
So with unversiones paged, the second request (which carries only a pageId in
URL in form /wicket/page?1...) does not find the page by id and the
PageProvider throws the exception in getPageInstance().
I think, that instead of explicitly touching the page, it should be done by
Wicket when retrieving the url for it. Somewhere in mapUrlFor or mapHandler,
etc...
Thanks for your patience.
David
