[rules-users] Delimited Number groups filtering ?

Hello, The dataModel is as following: class AgeRange() { Integer code; int minAge; int maxAge; } Campaign() { List<Integer> listOfAgeRangeCodes; } Subscriber() { int age; } AgeRange()'s and Campaign()'s are pre-populated into the WM. Subscriber() is asserted right before fireAllRules is called. I need a rule that would allow me to check if Subscriber() is within one of the defined on the Campaign() AgeRange()'s. What would be the most efficient way to enforce this constraint? The other possibility I see is to store the list of AgeRange()'s in each Campaign() and then use eval() to iterate over the list... Advice and ideas are appreciated. Thank you, Maxim. -- Cheers, Maxim Veksler "Free as in Freedom" - Do u GNU ?
