Re: [rules-users] Can I check if a collection contains one, and only one item of another collection

Thanks for your response. I don't think contains will work in this case. I need to match if a collection contains one, and only one, of another collection. So " ('a','b','c') contains one of ('a','b','e') " should not match, where "('a','b','c') contains ('a','2','3')" should match.
