I would recommend that you post the *real* struts.xml section that reproduces the problem.

> Trying to override one of three interceptor parameters in an action specific config using method #2 described in http://struts.apache.org/2.0.11.1/docs/interceptors.html#Interceptors-InterceptorParameterOverriding leaves the params that aren't overridden in the action (but defined in stack definition) null.  Unfortunately, the other two parameters that I'm not overriding are not being taken from the default stack definition and are ending up as null on the interceptor.  Below is a sample action config showing what I'm attempting...
> <package name="packageA"...>
>     <interceptors>
>         <interceptor name="myInterceptor" class="..."/>
>         <interceptor-stack name="myStack">
>             <interceptor-ref name="defaultStack"/>
>             <interceptor-ref name="myInterceptor">
>                 <param name="paramA">defaultValueA</param>
>                 <param name="paramB">defaultValueB</param>
>                 <param name="paramC">defaultValueC</param>
>             </interceptor-ref>
>         </interceptor-stack>
> </package>
> With the following action config, the "myInterceptor" interceptor's  paramA & paramB are null (causing the interceptor logic to break) and not "defaultValueA" and "defaultValueB" as expected/desired.
> <package name="packageB" extends="packageA"...>
>     <action name="myAction" class="myActionClass">
>         <interceptor-ref name="myStack">
>             <param name="myInterceptor.paramC">actionSpecificValue</param>
>         </interceptor-ref>
>     </action>
> </package>
> BTW...defining the action with all parameters overridden (see below) works:
> <action name="myAction" class="myActionClass">
>   <interceptor-ref name="myStack">
>      <!--  same value as defined in "myStack" declaration  -->
>      <param name="myInterceptor.paramA">defaultValueA</param>
>      <!--  same value as defined in "myStack" declaration  -->
>      <param name="myInterceptor.paramB">defaultValueB</param>
>      <param name="myInterceptor.paramC">actionSpecificValue</param>
>  </interceptor-ref>
> </action>
