Lukasz Lenart updated WW-4667:
------------------------------
Fix Version/s: 2.3.31
> ParametersInterceptor excludeParams only applies to first instance of params interceptor in paramsPrepareParamsStack
> --------------------------------------------------------------------------------------------------------------------
>
> Key: WW-4667
> URL: https://issues.apache.org/jira/browse/WW-4667
> Project: Struts 2
> Issue Type: Bug
> Components: Core Interceptors
> Affects Versions: 2.5.1
> Reporter: Chris Cranford
> Fix For: 2.3.31, 2.5.3
>
>
> 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.
