I think that you'll need to declare the param, something in the likes of...
<action name="actionparam"
class="test.ActionParam">
<result>/ActionParam.jsp</result>
{1} <!-- added this -->
<interceptor-ref name="servlet-config" />
<interceptor-ref name="params"/>
</action>
not sure though since I don't have the time to thoroughly look through the
code :p
