NPE when data is null

I get the impression that pivot does not handle null data very well. I get this on a roweditor and I did get it in another situation when the data model has some null elements.

java.lang.NullPointerException

Re: NPE when data is null

Posted by Greg Brown <gk...@mac.com>.
Are you using Pivot 1.4 or 1.5? I believe this may have been fixed for 1.5 - if not, please feel free to submit a bug report in JIRA.
