Subject [jira] Created: (STR-2989) NullPointerException on indexed properties only on session timeout

NullPointerException on indexed properties only on session timeout
------------------------------------------------------------------

                 Key: STR-2989
                 URL: http://issues.apache.org/struts/browse/STR-2989
             Project: Struts 1
          Issue Type: Bug
          Components: Core
    Affects Versions: 1.2.9
         Environment: Windows XP, WebLogic 8.1 
            Reporter: Steve Klosterbuer


I have an ActionForm that has a getter and setter for a Collection of Objects.  The jsp uses
the logic:iterate tag to output the indexed nested properties.  Everything works fine until
the session times out.  Then I get the following stack trace:
