[rules-users] not in -Not working

[Gopu Shrestha]

Here is the code snipet.

rule "Validation"
when
                $claim: Claim($cos: claimIdentificationInfo.categoryOfService !=null);
                $claimId: ClaimIdentification($cos not in ("01","03","04"), $cos.length >0);
then
                log.info("Executing Rule: Validation .............");
end

Above code works if
- $cos in ("01","03","04")
-$cos.length

But when I put not in front of in ("not in"), it throws exception like this...

Unable to build constraint as  '$cos' is invalid : [Rule name='Validation']
