Hi. I am trying to implement the following rule using a guided rule in
Guvnor. It works successfully in the Eclipse environment.
rule "SevereHypoglycemia"
no-loop true
when
$event : GlucoseEvent(input.glucoseValue <=
glucoseConst.severeHypoglycemiaThreshold);
then
GlucoseResult result = $event.getResult();
result.setNewInsulin(0);
double nextTime = glucoseCalc.calculateDuration(1.0,
$event.getInput().getGlucoseValue(), $event.getInput().getGlucoseTime(),
null, null);
result.setHoursToNextMeasurement(nextTime);
result.setDextroseGr(0.5);
result.setNotifyPhysician(true);
$event.setResult(result);
update($event);
System.out.println("SevereHypoglycemia rule ran.");
end
I have imported the jar file and can see all of the objects. The problem I
am having is with the nested object model. I can reference the
GlucoseEvent.input.glucoseValue field successfully, but the only comparison
operators I get are 'equals too' and 'not equals to'. They type of
glucoseValue is double and I need to do relational comparison as in the rule
above. If I do a 'View Source' on the rule in BRMS, this is what I see if
I use the 'equals' operator:
rule "Rule1"
dialect "mvel"
when
GlucoseEvent( input.glucoseValue == "40" )
then
end
Is this bug or does the guided rule editor only support flat object models?
Thanks,
Herman Post
