Sorry to have muddled the waters too much, I assumed too much...Having 
looked at the LookupDispatchAction code, I can now make a slightly more 
educated reply ;).

Yeah I think you're going to have to workaround the parent method.


public class DefaultLookup extends LookupDispatchAction {

public ActionForward execute(.....){
    if (request.getParameter(mapping.getParameter()) == null)  {

        return defaultMethod(....)
    } else return super.execute(....);
}

public abstract ActionForward defaultMethod(....) ;
}

This should work! i think...
