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,

Does it not compile (in which case can you post the error)?
Or does it not activate?

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).

Chris,
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.
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:
https://hudson.jboss.org/hudson/job/drools/lastSuccessfulBuild/artifact/t...
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.

Thank you for the snapshot build. It does seem to fix the problem (and also
the bugs you mentioned you fixed).

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,

With 4.0.2, I know of no showstopper bugs. But until Edson gave me the
SNAPSHOT build today, I did not have 4.0.2.

From the manual:
"A not statement must be followed by parentheses around the pattern that it
applies to. In the simplest case of a single pattern (like below) you can
omit the parentheses."
We improved the docs for the next version. Hope it is clearer now. But
Michael got it right.

Ok, the parenthesis makes sense.
But when I enclose the pattern as Michael suggested, it gets a runtime error
trying to parse. I attached a sample project illustrating this in an
earlier response. So isn't there still a problem?
