Hi.
I am experiencing the following exception:
org.drools.RuntimeDroolsException: Exception executing ReturnValue
constraint org.drools.rule.returnvaluerestrict...@a5f6c234 :
java.lang.NullPointerException.
The rule that is causing the exception to occur is the following:
rule spreadOvertime
Looks like an NPE in your rule.
Maybe maintenanceSlot or something is null.
You should raise an issue with drools-core (drools expert) that it
should give a better runtime error to show on which line it NPE'ed.
With kind regards,

Hello Edson,
Frankly, I wouldn't spend a lot of time on this. The alternate
approach is to inject the working memory into the Seam component as
described in the docs. Assuming that works (which I'm sure it will),
then there's no reason to use the approach I was attempting. Let me
Hello,
I downloaded Seam 2.0.0.GA, built the drools example (it's a simple
number guess application). It fails exactly the same way.
I'm guessing the Seam guys tested this before releasing, so I'm
assuming (as Edson pointed out) a JVM issue with Mac OS X Leopard?

Solved.
Actually, Mark Proctor solved this several days ago when he asked if
Seam came with its own Drools jars.
It does. If you use the non-Seam bundled drools jars, you will get
this exception. Sorry for wasting anyone's
time on this, but I'm curiousany ideas what is different

Fernando is taking a look in that.

Can you send me a pointer to the Leopard JVM bug? I haven't heard
about it (other than Java 6 isn't available yet).

If you want to do this yourself, it's quite simple:
1. Modify the examples/seamdiscs example in the Seam distribution by:
Maybe any of you can zip a small project showing this problem and send
me. I will dig down to find the problem and we can have an answer available
to all. This is for sure a classpath problem, so just a matter of finding
out exactly what is missing.

Hello Edson,
Eric was kind enough to reply that he solved his problem by
including ALL of the jars in the drools lib distribution directory in
his classpath -- not just the drools jars, mvel, and eclipse jars.
If I do this, JBoss 4.2.1 complains about not being able to parse its
xml
Robert,
Cool. Please keep us posted on your findings.

I'm not sure, but this problem existed prior to upgrading. To be
fair though, I didn't try the things I did today to remedy it.

I'm starting to use eclipse plug.in for JRules. I created the example JRules
