thanks for looking. I pasted the full stack trace below.  I am not using
any home grown action code (yet). This is coming from the
DefaultActionSupport during the rendering stage.

com.opensymphony.xwork2.DefaultActionInvocation.executeResult (DefaultActionInvocation.java:348)

Do I need to subclass and do something in the action.execute() code ?


here's the full trace
