Running Drools 4.0.3, on Win 2k sp4, JDK 1.6.0_03. I am getting this exception after the debugger shows execution has gone past the end of the rule. The exception is occurring in ReteTuple.get(Descriptor). I believe the descriptor argument is null. Can anyone suggest why this might be happening and what I can do to avoid it?

Nope, only source code.

Can you provide a self contained test to reproduce the problem and attach it to a JIRA? I will fix it. Thanks []s Edson 2008/4/9 Scott Reed <sreed(a)avacoda.com <mailto:sreed@avacoda.com>>: 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.
