I have a rule and it is supposed to retract two objects when $objectOne : ObjectOne(...) $objectTwo : ObjectTwo(...) then retract($objectOne); #retract($objectTwo); end No matter what I do I can't ever retract objectTwo. I put a print statement and it is there. If I comment out the retraction of objectTwo it works fine. I tried just retraction of objectTwo and that fails too. I tried prefixing with drools.retract. I get this: com.principal.health.rules.RulesException: Root exception: [Error: drools.retract($objectTwo): null] [Near : {...
