That’s fantastic Chris!  Thank you so much!


I believe TIER packaging folk have said they are waiting for you to do something to make 106 available for packaging.  I do apologize if this means more work for you.

Fixed in patch 2.3.0 API 106



Note, there is an error going on, and then when logging since that error happened, another error happened and masked the previous error.  So I think once you install this patch, you will still need to see whats going on.

Can you please send more logs?  There should be more stacks or more to the stack…

Subject: [grouper-users] NPE on loader sync


I have a loader job which seems to get through handling the memberships and then I get many NPEs on the job rather consistently but I can’t tell why.  I have looked at the code but what is running in the TIER package seems different from the current code and I am not sure which branch lines up with what is running. 


I have looked at what I am producing in the loader very carefully and the output really does appear to be good.


If I could get a better hint as to what the NPE really represents as to what I may be doing wrong with my output… I’d appreciate knowing.



I am seeing many of these NPE(s), one for each group having members:
