Re: [rules-users] NullPointerException with factType.get(fact, "fieldname")

Michael, I think the class is just incidentally named ValidationError. The problem is in the "wiring" of the accessors into the FieldDefinition (you see that "accessor=null" at the end of the toString in the failing case). This wiring is done by the PackageBuilder when the DRL is compiled, so I suspect that there is a problem with the interaction of the data modeller and the package builder.. Jarkko, thanks for reporting this, it really looks like a WB bug! Could you please open a JIRA ticket?
