[rules-users] Accumulator being executed depending on the number of events

Hi, I'm experimenting with Drools and have troubles understanding the way accumulators work. Before i go and look at the source code i was wondering if the way the accumulators work is designed as described below or of it has something to do with my rules configuration. I'm using drools distibution 5.4.0. So this is my test case: I have 3 similar events and 1 rule containing an accumulator. So when firing the alerts obviously as the events are similar the same rule is fired. So accorrding to me when the rule is fired drools creates a new accumulator and passed data for all events but at the same time the first accumulator still exists and receives only the datza for the second event. The 3rd event will trigger accumulate for context1 and context2 and then create a new accumulator with all the 3 events. This results in actually having 3 accumulators with exactly the same data. I have created a dummy accumulator to test this: Here is the DRL rule "update profile" salience 1000 // Make sure this rule is always executed by giving it a very high salience no-loop true when $event: TestEvent() $profile: Profile( key == $event.key) $total : Number() from accumulate( TestEvent( $p : value, key == $event.key), test( $p ) ) then System.out.println("Total:" + $total); end Here is the output Event 1 Context created:137 Init called for context:137 accumulate called for context:137 object:80 Total called for context:137 Total:80 Event 2 Context created:858 Init called for context:858 accumulate called for context:858 object:80 Total called for context:858 accumulate called for context:137 object:41 accumulate called for context:858 object:41 Total called for context:858 Total called for context:137 Total:121 Total:121 Event 3 Context created:724 Init called for context:724 accumulate called for context:724 object:80 accumulate called for context:724 object:41 Total called for context:724 accumulate called for context:137 object:53 accumulate called for context:858 object:53 accumulate called for context:724 object:53 Total called for context:724 Total called for context:858 Total called for context:137 Total:174 Total:174 Total:174 How can i remove the accumulator after the rule is finished?
