 What you need to achieve is that the URL stays stable. One way to
 achieve this is to use panel replacement. E.g. when you click the
 download page, you replace the main panel on your page with a panel
 that displays the license agreement. If you turn off versioning for
 that page, the URL will stay stable and thus if you push the back
 button later, your browser will return to the first version of the
 page. I think this should work for most browsers (maybe only not with
 Opera). There are alternative ways to do this, including throwing
 RestartResponseExceptions, using custom page factories and custom url
 coding strategies. Or you can trick the browser using JavaScript, of
 which I don't know too many details.

Re: [Wicket-user] Stable URLs (Was: Bookmarkable pages and transparent login)

2007-05-31 Thread Johan Compagner 

nothing is wrong if you click on a wicket link (or submit a form) then we do
a redirect
to the page that is then rendered

What is strange (if that happens at your place) is that if you click on a
bookmarkable link
then that link should stay there (until you press a none bookmarkable link
or submit a form on that page)
If you just click on a bookmarkable link and then the url does change in the
browser then somewhere
a setRedirect(true) is done.

Re: [Wicket-user] Stable URLs (Was: Bookmarkable pages and transparent login)

2007-05-31 Thread Thomas Singer 
 If you just click on a bookmarkable link and then the url does change in the 
 browser then somewhere
 a setRedirect(true) is done. 

So the URL http://localhost:8080/?wicket:interface=:2::; comes from the 
throw new RestartResponseAtInterceptPageException(this)? At least the second 
time, when getOurSession().isLicenseAgreed() returns true and hence no 
redirect happens, the URL remains the same.

Unfortunately, this does not allow me to eliminate the intermediate redirect 
to the license agreement from the back-button history, although 
isVersioned() returns false all the time.

that url that you get doesn't have anything to do with a page being
versioned or not.
that url you just get when you redirect to a page instance.
if you want to keep that bookmarkable then use this constructor

public RestartResponseAtInterceptPageException(final Class
interceptPageClass)

Thanks. One further question regarding links and bookmarkable pages: When I 
add following PageLink, will the resulting href always be not bookmarkable?

public class DownloadFile extends OurWebPage {

   public DownloadFile(final PageParameters parameters) {
 page.add(new PageLink(linkId, new IPageLink() {
   private static final long serialVersionUID = 1L;

   public Page getPage() {
 ...
 return getPageFactory().newPage(getPageIdentity(), parameters);
   }

   public Class getPageIdentity() {
 return DownloadFile.class;
   }
 }));
   }
}

Indeed. That is because you're using an inner class, and Wicket
wouldn't know how to interpret and can't do anything else than execute
it (for which it needs to be stored for a next request). When you just
provide a class argument otoh, Wicket knows enough to write this out
as a bookmarkable page link.

In other words: when something more should be done than just linking to 
another (bookmarkable) page, then always the resulting link is non-bookmarkable?

[Wicket-user] Stable URLs (Was: Bookmarkable pages and transparent login)

2007-05-30 Thread Thomas Singer

following page code:

   private static final String FILE_PARAMETER = file;
 
   // Static

   public static BookmarkablePageLink createLinkToPage(String id, String 
 file) {
   final BookmarkablePageLink pageLink = new 
 BookmarkablePageLink(id, DownloadFile.class);
   pageLink.setParameter(FILE_PARAMETER, file);
   return pageLink;
   }
 
   // Setup 
 ==
 
   public DownloadFile(PageParameters parameters) {
   final String file = parameters.getString(FILE_PARAMETER);
   if (file == null) {
   throw new 
 RestartResponseAtInterceptPageException(Download.class);
   }
 
   if (!getOurSession().isLicenseAgreed()) {
   addContent(createLicenseFragment(contentPanel, 
 parameters));
   throw new RestartResponseAtInterceptPageException(this);
   }
 
   addContent(createDownloadFragment(contentPanel, file));
   }
 
   // Utils

   private Fragment createDownloadFragment(String id, String file) {
   final Fragment fragment = new Fragment(id, downloadFragment);
   fragment.add(new Label(file, file));
   return fragment;

   private Fragment createLicenseFragment(String id, final PageParameters 
 parameters) {
   final Fragment fragment = new Fragment(id, licenseFragment);
   fragment.add(new PageLink(accept, new IPageLink() {
   public Page getPage() {
   getOurSession().setLicenseAgreed(true);
   return new DownloadFile(parameters);
   }

   return DownloadFile.class;
   }
   }));
   return fragment;

Every page is mounted with QueryStringUrlCodingStrategy. On the Download 
page a link to this DownloadFile page is created using the above
