[rules-users] Live Queries and Expired Events

I have a live query that should match *all* the events I insert. However, it's apparently not being called for a large number of them. It appears that if an event is expired at the time of insert, it's not tripping the rowRemoved part of the query. Is this the expected behavior? If so, is there so

Hello, I want to implement a simple scenario using Drools, but I can't find the right functions to do so. I have a class named Notif that represents my events. When I receive a Notif with a certain attribute (for example, type == "A") I want to get a list of all the events I receive in the next

Makes sense, pretty good explanation. Is there a way to turn this behaviour off? I don't want the rule engine to re-calculate the rules when I update a fact inside the rule engine. Is that possible? The reason I ask is that in my application it makes sense based on the way I have structured the ru
