Re: [rules-users] Retraction of facts based on time - any ideas please?

I have a need to "expire" some facts based on time. In other words, if an event occurs some time and if sufficient time has gone by, the fact should become inonsequential and be retracted. Here is my simple rule to do this: rule"Retract expired facts" dialect"mvel" // salience -5 when e1 : Event (code == "LOGON", status == "ACTIVE") eval ((getCurrentTimeStamp ()- e1.getLongTimeStamp()) > 100) then System.out.println( "Retracting expired event with Timestamp: " + e1.longTimeStamp ); retract (e1); end This does not seem to work because the "eval" method does not evaluate the rule every cycle. And, there is no other change to the fact (event) to force the rule to re-evaluate the fact. Is there a way to make "eval" in the LHS evaluate every cycle? Is there any other method? I would greatly appreciate any ideas.
