CEP - event both in and out of time window at the same time ----------------------------------------------------------- Key: JBRULES-3161 URL: https://issues.jboss.org/browse/JBRULES-3161 Project: Drools Issue Type: Bug Security Level: Public(Everyone can see) Components: drools-core Affects Versions: 5.2.0.Final Environment: jre 6u24, windows 7 x64 Reporter: Radai Rosenblatt Assignee: Edson Tirelli Priority: Critical Attachments: droolsbug.zip, illustration.jpg given this object: public class Event { private Date started; private Date finished; private long duration; //getters and setters } the following drools code: declare Event @role( event ) @duration ( duration ) @timestamp( started ) end rule "Event Exists In Window" when $eventOne : Event() over window:time( 1h ) from entry-point "Event Stream" then //nothing end rule "No Event Exists In Window" when not ( Event() over window:time( 1h ) from entry-point "Event Stream" ) then //nothing end and the following scenario: [miserable attempt at ascii art replaced by attached image] (an event at time T that start at T-1.5h and ends at T+1h) both of the above rules fire. im not sure which of them _should_ fire for this scenario, but im pretty sure its either one or the other (to my understanding the conditions are logically exclusive - there either exists an event in the window or there doesnt)
