Re: [rules-users] Test for null object, not null property

The incoming building was initialized like this: Building building = null; FactHandle buildingFact = businessRuleSession.insert( building ); businessRuleSession.setFocus("validate delete or get building"); businessRuleSession.fireAllRules(); Can drools test for this null building? What should the rule look like? rule "building is null" agenda-group "validate delete or get building" salience 10 when boException : BOException() Building() == null /* this is the problem here -- not sure what this should look like */ then boException.setCode("BO-0008"); end _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
