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?

Brian.

Subject: Re: LookupDispatchAction default
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.
