ActionServlet doesn't react when Action returns null

Hello all,

my impression is, when an Action returns null like:
   
   ActionForward forward = mapping.findForward("some_forward");     // this
forward is not declared in the configuration file !!!
   return forward;  // return null;


the ActionServlet does not react propper.  It does not handle this
situation.

Wouldn't it be better to return a  HTTP-Error ?

Best regards, fm

A null return value from your Action is essentially saying "my Action has
created the response already, so there is no need to forward anywhere
else."  This is documented in the JavaDocs for the
<code>Action.perform()</code> method.
