<br> Sergey,<br><br> That is how it is supposed to work. A field constraint in Drools always has a field at its left side. If you want arbitrary expression, just embed it in an inline eval:<br><br> S : Supplier(
<br> $sts : supplierBusinessStatus.businessStatus,<br> $csts : corporateSupplier.supplierBusinessStatus.businessStatus, <br> eval ( $sts != $csts ) <br> )
<br><br> Although, for this specific case, it would be better (more performatic) to simply write:<br><br> S : Supplier(<br>
$sts : supplierBusinessStatus.businessStatus,<br>
$csts : corporateSupplier.supplierBusinessStatus.businessStatus != $sts<br> )<br>

<br>Folks,<br><br>I found that drools 4.0GA doesn't recognize variables in the left side<br>of operator expression<br><br>Like this produces error:<br><br><br>When<br> S : Supplier(<br> $sts : supplierBusinessStatus.businessStatus
