Actually, it is still broken.
This does not complain but it always executes the consequence, even when the
stateLicensures includes the state that in patientDetails.state
$ca:CandidateAssociation(nurseDetails.stateLicensures not contains patientDetails.state
)
I also tried the following but it complains with an Exception
$ca:CandidateAssignment(participantDetails.state not memberof
nurseDetails.stateLicensures )
org.drools.rule.InvalidRulePackage: [13,50]: unknown:13:50 Unexpected token
'not'[13,93]: unknown:13:93 mismatched token:
[@98,574:574=')',<13>,13:93]; expecting type LEFT_PAREN
at org.drools.rule.Package.checkValidity(Package.java:408)
at org.drools.common.AbstractRuleBase.addPackage(AbstractRuleBase.java:288)
Is what I am trying to do supported by Drools?
Thank you,
Mark

My rule now appears to be working after switching from the
"excludes" operator
to the newer "not contains".
This works:
$ca:CandidateAssociation(nurseDetails.stateLicensures not contains
patientDetails.state )
This does not:
$ca:CandidateAssociation(nurseDetails.stateLicensures excludes
patientDetails.state )
