Matias Rodriguez commented on WW-4390:
--------------------------------------
Hi! I believe that this issue is present on struts2-core 2.3.24. I'm using the
following configuration:
...
{code:xml}
<interceptor-ref name="paramsPrepareParamsStack">
<param name="params.excludeParams">^action:.*,^method:.*,_</param>
</interceptor-ref>
{code}
...
But the excludeParams is only consider at first params interceptor. The output
is:
{noformat}
[2015-05-24 20:00:57,224] WARN (CommonsLogger.java:60) - Parameter [_] matches
excluded pattern [_]!
[2015-05-24 20:00:57,281] ERROR (CommonsLogger.java:34) - Developer
Notification (set struts.devMode to false to disable this message):
Unexpected Exception caught setting '_' on 'class
action.flota.EventoMovilAction: Error setting expression '_' with value
['1432508453195', ]
{noformat}
Thanks in advance!

> Project: Struts 2
> Issue Type: Bug
> Components: Core Interceptors, Plugin - Convention
> Affects Versions: 2.3.16.3
> Reporter: Fabian Richter
> Assignee: Lukasz Lenart
> Fix For: 2.3.20
>
>
> 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,
