PageActivationContext Coercion Exceptions
I have an app with several pages like:
www.app.com/itemInfo/1
where 1 is the page activation context and gets coerced into the
object using Tapestry-Hibernate. This works great, but... the graphic
designer accidentally added a link into the header without the http. I
fixed it, but not before Google indexed the site. Now the GoogleBot
keeps calling urls like:
www.app.com/itemInfo/www.example.com
Obviously www.example.com can't be turned into a Long and then into
the object so it gives an exception.
Is there an easy way to globally say, "if type coercion fails, just
return a 404?" If not is there a way to catch the exception?

Thanks, Kalle. I'll check that out.
I also found that you can intercept the exceptions which I had
overlooked in the docs:

I haven't tried, but using tapestry-exceptionpage
(http://tynamo.org/tapestry-exceptionpage+guide) you should be able to
map UnknownValueException to your 404 page.
