-----------------------------------
Lukasz,
No this is not in dev mode.
And thanks for the explanation, I now understand what is cauing my issue. I
also just noticed that the params I was blacklisting, was no longer being
blacklisted in 2.3.7 because of the change you mentioned. in 2.3.4 and previous
using the ParameterNameAware allowed to blacklist stuff, now it behaves a lot
differently since it seems to only be triggered for things that are already
blacklisted using a different method (which is I guess the params.excludeParams
parameter).
I was using this method because I did not know about the excludeParams
parameter, now that I do, I will get rid of all the ParameterNameAware stuff
since it no longer does what I want it to do.
Bruce,
Thanks for your help, the code suggestion you made would work to remove the
warning, but since the ParameterNameAware no longer does what it use to do, I
will be just adding my blacklist to params.excludeParams instead and getting
rid of the ParameterNameAware stuff.
I agree that it might be a good idea to add some stuff to ParameterNameAware to
explain that it no longer really functions as a blacklist, and instead
functions as an override on the excludeParams blacklist.
As far as I am concerned the issue is closed. But I will leave it to you to
close incase there is anything else you want to add.
Thanks,
Shawn

> Project: Struts 2
> Issue Type: Bug
> Components: Plugin - Portlet
> Affects Versions: 2.3.7, 2.3.8, 2.3.12, 2.3.14, 2.3.14.1, 2.3.14.2,
> 2.3.14.3, 2.3.15
> Environment: liferay portal running in tomcat
> Reporter: Shawn Andrews
> Assignee: Bruce Phillips
> Priority: Minor
> Fix For: 2.3.16
>
>
> I tried to migrate some portlets from 2.3.4 to 2.3.7 (actually to 2.3.15 but
> have found that the problem starts in 2.3.7)
> What happens is there is now a warning in the logs whenever I execute an
> action.
> 09:33:35,327 WARN [OgnlValueStack:60] Error setting expression
> 'struts.portlet.action' with value '[Ljava.lang.String;@78f28bba'
> ognl.OgnlException: source is null for getProperty(null, "portlet")
> It seems that in older versions of struts portlet plugin this parameter use
> to be taken out, since I believe it is used by struts2 to know what action
> to execute, but should maybe not be stored in the OGNL stack. My guess is
> that this has to do with no field called 'portlet' with property 'action' in
> my action class existing to place the expression.
> In version 2.3.4.1 and previous this was not an issue. Maybe the portlet
> interceptor was taking this parameters out before it was placed into OGNL,
> and now it is being left?
