Andy-
the short answer is you don't want 
user-set parameters to override your static parameters.


btw for 2.1.1 you also need: "actionMappingParams"


Which means your stack should be:

<interceptor-stack name="paramsPrepareParamsStack">

.......
<interceptor-ref name="params"/>

<interceptor-ref name="actionMappingParams"/>

<interceptor-ref name="staticParams"/>

...

<interceptor-ref name="prepare"/>

...

<interceptor-ref name="params"/>

<interceptor-ref name="actionMappingParams"/>

<interceptor-ref name="staticParams"/>


</interceptor-stack>
