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
