Well, I tried overriding unspecified and I still get the following 
(mind
you that I didn't change the parameter name yet) when I hit
/admin/list.do:

        Error 500: Request[/admin/list] does not contain handler 
parameter
named submit

My unspecified method I simply overrode from DispatchAction to call my
normal refresh list method:
        protected ActionForward unspecified(
                ActionMapping mapping,
                ActionForm form,
                HttpServletRequest request,
                HttpServletResponse response
        ) {
                return this.refreshList(mapping, form, request, 
response);
        }

While the JavaDocs do imply this should work, when I looked in the 
Struts
1.1 source, the execute method of LookupDispatchAction generates the 
erorr
message I see as soon as request.getParameter(parameterName) returns 
null.
 In fact, I can find no reference to 'unspecified' anywhere in
LookupDispatchAction.

So I think there is a disconnect.  Maybe LookupDispatchAction is broken
and should be fixed to also use 'unspecified', or maybe its JavaDocs
should explicitly state that it does not utilize the 'unspecified'
behavior of its parent class.  Or, maybe I missed something and didn't
implement correctly?

unspecified() is the method you want look at the javadoc.

you do need the method name though

/admin/list.do?method

I saw that using "submit" as the parameter name causes problems so i
wouldn't use that.

I'd like to be able to have someone hit my action, /admin/list.do,
without
having to specify a submit paramater.  However, the action is a
subclass
of LookupDispatchAction whci requires that the request parameter be
supplied.  Looking in the struts source code, it would be nice if the
LookupDispatchAction could fall back to a default or not consider
'null'
to be a bad value and just use 'null' as a key to the lookup Map.  For
now, any link or redirect to the page must specify what I consider to
be
the default action -- refresh -- on the URL:
/admin/list/do?submit=Refresh.
Is there another way to do this?  Is it worth suggesting that
LookupDispatchAction support a default or null mapping?
