Hi,
I'm currently trying to use RestartResponseAtInterceptPageException with
Ajax. More precisely, I show a component that refreshes itself after
executing an authorized action. It the user is not authorized to execute
this action, I'd like to redirect him to the Login-Page. After proper login,
the user should be redirected to the original page. However, using
continueToOriginalDestination() does not work (out of the box), as the User
is redirected to the URL of the Ajax request.
Workaround/Possible changes to simplify workaround:
A custom workaround would be to do a custom PageMap implementation. However,
as the method setUpRedirect(RequestCycle) is private, deriving from the
default PageMap will require some ugly copy-paste in order to do so. This
could be avoided by a) making setUpRedirect(RequestCycle) protected and/or
b) introduce a protected method that constructs the interceptContinuationURL
inside setUpRedirect(RequestCycle).
Changing default behaviour:
The workaround version is not trivial, as in requires quite a bit of
knowledge of Wicket's inner workings ("What the hell is a PageMap?").
Therefore, it might be a good idea to change the default behaviour there, as
no user wants to see Ajax responses at all (well, at least no normal user -
I really enjoy their unrivalled beauty ;) ). Shouldn't the behaviour be
somewhat more intelligent by default (without hacking a custom PageMap)?
That is to redirect to the page the Ajax request belonged to? Or even
better: redirect to the Ajax call and render the complete page (well, don't
know how tricky that would be).
Or do I miss something completely? Any other possible workarounds or
suggestions?
Cheers, Stefan
