             Summary: Getting NPE on each request while upgrading from 
Strutsv2.2.1.1 to Strutsv2.3.37
                 Key: WW-5223
                 URL: https://issues.apache.org/jira/browse/WW-5223
             Project: Struts 2
          Issue Type: Bug
            Reporter: sowjanya


We are upgrading from Strutsv2.2.1.1 to Strutsv2.3.37. Added all Struts 
dependencies but getting NPE in action class.

We noticed this issue is caused as parameter values are not setting in the 
setter.
