Sergey,
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:
S : Supplier(
$sts : supplierBusinessStatus.businessStatus,
$csts :
corporateSupplier.supplierBusinessStatus.businessStatus,
eval ( $sts != $csts )
)
Although, for this specific case, it would be better (more performatic)
to simply write:
S : Supplier(
$sts : supplierBusinessStatus.businessStatus,
$csts :
corporateSupplier.supplierBusinessStatus.businessStatus != $sts
)
