Anyone know why the error handling is different in these
two Action classes when the parameter is missing from
the request?

DispatchAction calls the unspecified() method, but
LookupDispatchAction throws an exception that can not
be caught in the application.

Why isn't LookupDispatchAction calling the unspecied()
method as well?

I wouldn't call this a bug (a very annoying feature, at
least for me), but from reading the javadoc for the
DispatchAction.unspecified() method, it looks like the
method was added in later to allow application developers
to create their own default behavior when the dispatch
parameter isn't specified. I think the same behavior
should be present in LookupDispatchAction as well.

Any comments?
