---------------------------------
Summary: Parameter warnings being generated in logs after 2.3.7 in
portlet
Key: WW-4137
URL: https://issues.apache.org/jira/browse/WW-4137
Project: Struts 2
Issue Type: Bug
Affects Versions: 2.3.15, 2.3.14.3, 2.3.14.2, 2.3.14.1, 2.3.14, 2.3.12,
2.3.8, 2.3.7
Environment: liferay portal running in tomcat
Reporter: Shawn Andrews
Priority: Minor
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?
