we still have bugs which stop you upgrading?

Attached is the eclipse project that illustrates the problem. I use
Drools 4.0.0, and have not tried this code with 4.0.1 (since bugs in
it keep me from upgrading until 4.0.2).

Does it not compile (in which case can you post the

Or does it not activate?

Hello,
Does anyone know why rule "GoodBye2" below does
not compile, but rule "GoodBye1" does compile
using Drools 4.0.0? The only difference is the
"not". Shouldn't this be valid?
Thanks,
-Chris
