> The default URL strategy in wicket throws IllegalStateException, when there is odd number of parameters ?
> See AbstractRequestTargetUrlCodingStrategy: line 169 in RC1
> We have a problem with this way handling, because our users rewrite URLs manually
> (we cannot prevent users from doing this).
> Our pages are stateless and they don't use any parameters - BUT there are throwing exceptions
> and showing InternalErrorPage-s. It is presented like a serious problem like DB, or like service failed
> but there is no problem actually - only parameters, that are not used.
> I think, that page parameters should not result in INTERNAL ERROR,
> because there are many cases, where this is not relevant.
> There should be an alternative way - some custom handling or ignoring parameters in such a situation.
> The same problem is with MixedParamUrlCodingStrategy:
> (See MixedParamUrlCodingStrategy: line 181)  in RC1
> ------------------------------------------------------------------------------------
> Adding additional parameter results in exception a internal-error page.
> IMHO, additional parameters should be ignored and not result in error.
> I would suggest add the latest odd parameter to page parameters, but with empty value "".
