ForceEagerActivationOption and "not()" LHS pattern does not invoke matchCreated listener ---------------------------------------------------------------------------------------- Key: DROOLS-1256 URL: https://issues.jboss.org/browse/DROOLS-1256 Project: Drools Issue Type: Bug Components: core engine Affects Versions: 7.0.0.Beta1 Reporter: Matteo Mortari Assignee: Matteo Mortari Priority: Minor Given the following rules {code:java} rule ND when not ( Double() ) then // do nothing. end rule ND2 salience 1 when not ( Double() ) then insert( new Double(0) ); end {code} and KieSession created with {{ForceEagerActivationOption.YES}} and a generic AgendaEventListener on fire all rules returns: {code:java} created: 0 cancelled: 1 fired: 1 {code} hence incoherent as matchcreated . Expected: created=2, cancelled=1, fired=1. Reporting this as also I understand this eager option is used by jBPM.
