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).<br><br>-Chris<br><br><div><span class="gmail_quote">

<div></div>Hello,<br><br>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?
