[rules-users] Problem with BRMS (null and modify with variable)

Hi, When I try to compare an attribute against a null I got a "null" instead... the field is an Object. (Date). When I try to modify an attribute using the last value captured on LHS, I cant use the variable name in the textfield. The field type is numeric, but I need to use a formula ($var + 1) to modify the value in the BRMS. rule "Age uninformed" no-loop true ruleflow-group "age" when $p: Person(birthDate == null, $score: score) then $p.setScore($score + 5); update($p); end Do I have to open a Jira for this? Also: I didnt see a Jira, but Is it possible in the business rules editor to add new multiple comparators in new lines??? Like this: $p: Person(codProfession == 103 || == 201 || == 203 || == 204 || == 211 || == 218 || == 220 || == 403 ) Because actually this is aranged in the right side making it dificult to manage when you have several comparatos...
