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?
Thanks,
Scott
