<br> Chris,<br><br> I just tested your example and it works fine in 4.0.2.SNAPSHOT. We fixed a long list of bugs from 4.0.0 to 4.0.1/4.0.2, so I guess this is one of them.<br> My suggestion for you is: since you will need to update anyway and we fixed the bugs you reported in JIRA, get and test the latest binary from here:
<br><br><a href="https://hudson.jboss.org/hudson/job/drools/lastSuccessfulBuild/artifact/trunk/target/">https://hudson.jboss.org/hudson/job/drools/lastSuccessfulBuild/artifact/trunk/target/</a><br> <br> The only changes we expect to do in it for the
4.0.2 release are IDE changes, so it is very close to what you will get when it is released.<br><br> []s<br> Edson<br><br><br><div><span class="gmail_quote">2007/10/4, Chris West <<a href="mailto:crayzfishr@gmail.com">

<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?
