I am working on writing a rule to figure out which shadow fact in a group has the latest timestamp. Then use the found out in another rule. All shadow facts are the same java object and the size of the group is changable. If there are only two in the group I know how to achieve the goal, but more than two in a group I could not figure out how to do it. Can someone please help!!!
Thanks in advance

Forgot one more thing. I know if I always retract the shadow fact which has the older timestamp then I will only have the latest left. But I may need the old facts to stay in for other rules. So the question should be without retracting any facts how to find out which one is the latest.
