Hello,
Please excuse me if I have double posted - my first did not seem to appear.
I am wondering if the following is valid rule syntax. I am getting a
stacktrace when the rules fire that points to a ClassCastException on a HashSet
I am using v4.0 GA.
Thank you, Mark
rule StateMatch
when
$ca:CandidateAssociation(nurseDetails.stateLicensures excludes
patientDetails.state )
then
retract( $ca );
end
public class CandidateAssociation {
private PatientDetails patientDetails;
private NurseDetails nurseDetails;
private int overlapHours;
public CandidateAssociation( PatientDetails patientDetails,
NurseDetails nurseDetails) {
super();
this.patientDetails = patientDetails;
this.nurseDetails = nurseDetails;
overlapHours =
participantDetails.getNumberOverlapHourCnt(nurseDetails);
}
[...]
}
public class NurseDetails {
private Set stateLicensures = new HashSet();
[...]
}
public class PatientDetails {
private String state;
[...]
}
