Hi everyone!
I'm loading from Guvnor5.3.0 the pkg below into my application.
package org.dfms.model;
import org.dfms.model.observation.ACObservation;
import org.dfms.model.situation.AccessControlEvent;
import org.dfms.model.situation.SituationManager;
import org.dfms.model.situation.Event;
import org.dfms.model.mapfeature.AccessControlPoint;
import java.util.HashSet;
import java.util.ArrayList;
declare ACObservation
@role(event)
end
declare AccessControlEvent
@role(event)
end
rule "AccessControl"
no-loop
when
$obs : ACObservation( $sensorid : sensorId, $location : location ) over window:length(1) from entry-point access_control
then
insert( SituationManager.createAccessControlEvent( $obs, "Access Control Detection", Event.THREAT_NO, $location, $sensorid ));
end
When the rule is executed the application get this exception:
[java] ERROR [2012-07-20 14:32:17,422] [Thread-19] (ExpertSystemManager.java:162) - java.lang.NullPointerException
