> I typically extend the existing stacks with my own interceptor references on an as needed basis, as shown below.  
> The problem I face is that when I use the {{paramsPrepareParamsStack}}, I am noticing that the ParametersInterceptor excludes the custom defined entries on the first instance of the named {{params}} interceptor; however the second instance in the stack ignores these settings.
> {code}
> <interceptor-stack name="customStack">
>   <interceptor-ref name="myCustomInterceptor" />
>   <interceptor-ref name="paramsPrepareParamsStack">
>     <param name="fileUpload.maximumSize">20480000</param>
>     <param name="params.excludeParams">
>       dojo\..*,^struts\..*,^session\..*,^request\..*,^application\..*,^servlet(Request|Response)\..*,parameters\...*,submit,myObject\..*
>     </param>
>   </interceptor-ref>
> </interceptor-stack>
> {code}
> I suspect the code is likely just applying the parameters to the first named instance and breaking the loop rather than making sure _all_ instances of the named interceptor have the parameters applied correctly during Struts2 bootstrapping.
> The only workaround I've found is to avoid using the provided interceptor stack directly and copy it into my custom stack and explicitly set the excludeParams explicitly on both _params_ interceptor instances.
