Subject [jira] [Commented] (PIVOT-927) Unexpected NPE
Date Wed, 30 Oct 2013 04:17:25 GMT

    [ https://issues.apache.org/jira/browse/PIVOT-927?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13808729#comment-13808729

Łukasz Hanusiak commented on PIVOT-927:
---------------------------------------

It's a little embarrassing to acknowledge but whole maven version problem I traced back to
our local Artifactory server. After flushing repository caches current version of pivot 2.0.3
was successfully downloaded. Sorry for inconvenience. 

So I will try to rebuild my app and see if problem still occurs after upgrade. Thanks a lot
for your help and patience. 

I will try too look into this pivot-java-test-maven project later today.

> After mentioned exception occurs user is unable to use any element of UI. Only application
restart helps solve this problem. Even more confusing is fact that problem sometimes occurs
after few minutes and sometimes after few hours or even days. 
> Can anybody give me some pointers how to workaround / fix this situation?
