[rules-users] Reasoning with past events

I'm using Drools for a system of alarms on agriculture. I am considering several parcels, whose plants can be on different status (for example, sprouting, flowering, etc.). These statuses are updated automatically by rules, controled by several calendars. In the other hand, the farmer is allowed to change the plants' status by hand if he/she observes that real plants are in a status in the terrain. If the farmer set the status before the automatic change, there is no problem: the rules corresponding to the new state become active and the automatic change has no effect. But if the farmer changed the status after the automatic change, how would I consider the events in the period of time between automatic and hand changes? Thanks in advance. -- View this message in context: http://drools-java-rules-engine.46999.n3.nabble.com/Reasoning-with-past-e... Sent from the Drools - User mailing list archive at Nabble.com.
