Redire
Hi all,
pls is there a way to react to certain type of exceptions and redirect
the request to a page?
I think I saw somathing, but I can't find it.
I can't wrap it in RestartResponseAtInterceptPageException as in my
case it's thrown from within Wicket's code.
So, I'm looking for something like
getApplicationSettings.setExceptionMapper( new ExceptionMapper()
// Type,
Destination
.add( Exception.class,
ExceptionPage.class )
// Component of origin, Type,
Destination
.add( LoginPage.class, Exception.class, ExceptionPage.class
)
);
Or maybe just some exception handler with onException(), like
http://blog.wizche.ch/2011/12/wicket-15custom-exception-page.html - is
that the way? Not that convenient but usable.
Thanks,
Ondra

I would redirect to that page, and inform that processing this or that
failed.
Of course, the app shouldn't leak exceptions like that and they should
be caught at right places...
But that's a perfect state, and until that's reached, this could make
the app a bit more robust. But having just the exception is good enough.

No
But what would you do if you know that SomePanel did it ?

Found IExceptionMapper // Re: Redirecting on Exception - some

Posted by Ondrej Zizka <oz...@redhat.com>.
Aah, just found in the referenced wiki:
https://cwiki.apache.org/WICKET/migration-to-wicket-15.html#MigrationtoWicket1.5-Exceptionhandling
or override org.apache.wicket.Application.getExceptionMapperProvider() -
the IExceptionMapper is used if none of the configured
IRequestCycleListeners doesn't know how to handle the exception.
For information on how the request cycle handles exceptions see
RequestCycle in Wicket 1.5 for more information
So I would use BookmarkablePageRequestHandler or such.
Nice... Wicket is like having Christmas all year :)
But still:
I only get the exception. Ok, it has a stacktrace. But for convenience,
is it possible that I could get the component it came from?
