[jira] [Created] (WW-3942) NullPointerException in IteratorComponent

Charles Galpin created WW-3942:
----------------------------------

             Summary: NullPointerException in IteratorComponent
                 Key: WW-3942
                 URL: https://issues.apache.org/jira/browse/WW-3942
             Project: Struts 2
          Issue Type: Bug
    Affects Versions: 2.3.7
            Reporter: Charles Galpin


We get a NullPointerException from line 383 of IteratorComponent.java. The line is currently

return value != null ? values.get(nextIndex) : nextIndex;

and I believe it should be

return values != null ? values.get(nextIndex) : nextIndex;

values not value.

Exception below.

Exception created : java.lang.NullPointerException
        at org.apache.struts2.components.IteratorComponent$CounterIterator.next(IteratorComponent.java:383)
        at org.apache.struts2.components.IteratorComponent.start(IteratorComponent.java:302)
        at org.apache.struts2.views.jsp.ComponentTagSupport.doStartTag(ComponentTagSupport.java:53)
