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.Thanks,Dave CracauerOn Aug 23, 2008, at 8:31 AM, Scott Burrows wrote:You have the answer in your example, reserved word "contains" will give you that information._______________________________________________

Hi,
I'm getting stuck on this and I'm hoping someone can help..
I need to be able to check that a collection contains one, and only one item
from another collection.
Ideally, I would do something like this:
a:Answer(responses contains one of ("a","b","c"));
Is there a way do do this without resorting to evals or predicate
expressions? (drools 4.07)
Thanks,
Dave
