> Key: WW-4390
> URL: https://issues.apache.org/jira/browse/WW-4390
> Project: Struts 2
> Issue Type: Bug
> Components: Core Interceptors, Plugin - Convention
> Affects Versions: 2.3.16.3
> Reporter: Fabian Richter
> Fix For: 2.3.18
>
>
> When using paramsPrepareParamsStack with the convention plugin multiple
> duplicate errors/warnings with devMode=true occur like:
> {noformat}
> Error setting expression 'token' with value
> ['5UVO47K811DQ15DUZF4QV2NQ8DHIHSUY', ]
> Error setting expression 'token' with value
> ['5UVO47K811DQ15DUZF4QV2NQ8DHIHSUY', ]
> {noformat}
> By excluding these params (important is 'token') I was able to get rid of the
> duplication of these messages:
> {code:java}
> @InterceptorRefs({@InterceptorRef(value = "paramsPrepareParamsStack", params
> = {"params.excludeParams",
> "struts.token,struts.token.name,token"})})
> {code}
> But apparently only the first params interceptor in the stack uses these
> params. The second one (the one after the prepare interceptor) only uses the
> built-in excludeParams. So one of the above mentioned errors persists,
