Well you could simply call the view runmode after the update runmode has
run, but there are two recommended ways -
CGI::Application::Plugin::Forward and CGI::Application::Plugin::Redirect.
I prefer the latter, as a refresh of the browser doesn't resubmit the data
(which the first two methods would)
