Subject [jira] [Commented] (WW-4390) paramsPrepareParamsStack ignored excludeParams parameter in second params-Interceptor
Date Mon, 25 May 2015 05:52:17 GMT

    [ https://issues.apache.org/jira/browse/WW-4390?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14557990#comment-14557990

Lukasz Lenart commented on WW-4390:
-----------------------------------

You should not use {{params.excludeParams}} as this overrides the params defined internally,
see http://struts.apache.org/docs/s2-024.html

>          Components: Core Interceptors, Plugin - Convention
>    Affects Versions: 2.3.16.3
>            Reporter: Fabian Richter

> 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,
