[rules-users] "not contains" on Java5 enumeration

[Ray Ploski]

I'm not certain, but it looks like the Operator "not contains"[1] works 
fine with strings but not Enumerations.  Would someone please confirm or 
correct the rule syntax?  Thank you.


Given:


rule "Absence_Accumulation_Rule"

  when
    $slice : TimeSlice(
      classifiers contains(TimeSliceClassifiers.ABSENCE),
      classifiers contains(TimeSliceClassifiers.OT),
      classifiers not contains (TimeSliceClassifiers.COUNT_TO_FLSA),
   then
      System.out.println("Absence: Count to overtime but not FLSA");
end




public enum TimeSliceClassifiers {

     INSIDE_SCHEDULE,
     OUTSIDE_SCHEDULE,
     WORKED,
     ABSENCE,
     APPROVED,
     OVERTIME_REQUEST,
     CASH,INVOLUNTARY,
     COUNT_TO_OT,
     COUNT_TO_FLSA,
     OT,
     STRAIGHT,
     PREMIUM,
     EC0100,
     EC1400,
     EC1405
}




public class TimeSlice {
     private Date start;
     private Date end;
     private int elapsed;
     private Set<TimeSliceClassifiers> classifiers;
     private boolean sliceCreatedByRules = false;
}




Provides the following error:
[ERR 103] Line 110:21 rule 'in_key' failed predicate: 
{(validateIdentifierKey(DroolsSoftKeywords.IN))}? in rule 
"Absence_Accumulation_Rule" in pattern TimeSlice
