Re: [rules-users] How to trigger update when modifying a list attribute?

Hi, Thanks for your answer. Yes, Object was just a example, maybe I've used a bad one. I will try to invoke update to see whether it get modified. Could you tell me a little bit more about "superSetOf" ? How do I use it or where do I get more info about it? Didn't find anything on drools expert docs. Thanks very much.
