Subject [jira] [Updated] (WW-3942) NullPointerException in IteratorComponent
Date Thu, 13 Dec 2012 07:27:21 GMT

     [ https://issues.apache.org/jira/browse/WW-3942?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Lukasz Lenart updated WW-3942:
------------------------------

    Description: 
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.
