[rules-users] bug or feature not yet implemented

Folks, I found that drools 4.0GA doesn't recognize variables in the left side of operator expression Like this produces error: When S : Supplier( $sts : supplierBusinessStatus.businessStatus, $csts : corporateSupplier.supplierBusinessStatus.businessStatus, $sts != $csts ) Then ... It tries to treat the $sts variable as a field of Supplier, instead understanding that it is a variable declared earlier, Please advise, Thanks, -Sergey ********************** ** LEGAL DISCLAIMER ** ********************** This E-mail message and any attachments may contain legally privileged, confidential or proprietary information.
