Re: [rules-users] NPE after rule consequence executes

I am seeing the same ReteTuple.get( Declaration ) NPE when I run the app with both 4.0.7 jars. If this is a known bug, it appears not to have been fixed in this version. Edson Tirelli's message received 4/9/2008 8:05 PM: yes, the error in a test would stop the build process. Use the skip option I mentioned in my other e-mail.
