Hello,
What is the best practice for reusing rules? I've got a license number validation rule that I need to reuse for different fact types. For example, the first rule uses the license number in a CitationDTO fact:
rule "Citation DL Number"
ruleflow-group "CitationEntryValidationFlow"
when
CitationDTO($dln : citationSubject.driverLicense.driverAuthorizationId not matches "^.{5,15}$")
then
resultHolder.setMessage(GenericCitationFieldIds.DLN,"DLN [{0}] must be at least 5 characters long and no more than 15 characters long.", new Object[]{$dln});
end
Then I have another rule that uses the license number from the InCourtSearchDTO:
rule "InCourt DL Number"
ruleflow-group "InCourtSearchValidationGroup"
when
InCourtSearchDTO( $d : dln not matches "^.{5,15}$")
then
resultHolder.setMessage(UserLogonFieldIds.END_DT,"DLN [{0}] must be at least 5 characters long and no more than 15 characters long.", new Object[]{$d});
end
Obviously this is a poor implementation because the license number check 'not matches "^.{5,15}$"' is duplicated. Is there a way I can reuse this rule?
Thanks!
