(Using wicket 1.3.2) I have a super class (WebPage) that throws a
AbortWithWebErrorCodeException(404) depending on some properties of its
subclasses. Therefore I can't check the subclasses' properties in the super
class' constructor and throw the exception there.
So I tried to throw it in the onBeforeRender method instead. The Error page
for the 404 gets rendered and displayed without problems however an
exception gets thrown (see below).
So my question: where's the (right) place to throw the exception? I also
tried RequestCycle.get().setRequestTarget(new
WebErrorCodeResponseTarget(404)); with the same result.
thanks in advance
