I'm trying to add my convert and to convert empty parameters to null values.
But it seems that in such case, OGNL takes the null value as a signal that
conversion was not successful. So it backs up to using original String[] as
method argument, which simply doesn't work.

How should I deal with that? I'm trying to catch the conversion problems in
my customized ParameterInterceptor, but it seems that I have OgnlException
for every null value.

As far as I can see this is related to poor handling of exceptions in Ognl
itself... does anybody know if there are some changes to Ognl planned to fix
that?
