It seems that activation-group rule attribute is ignored when rule works with events (@role(event)). Example rule file: declare LocalEvent @role(event) end rule "Rule1" activation-group "test" when $event : LocalEvent() then System.out.println("I am rule 1 " + $event); end rule "Rule2" activation-group "test" when $event : LocalEvent() then System.out.println("I am rule 2 " + $event); end If i create event and insert it into KieSession both rules are fired, if i remove @role(event) line then only one rule is fired. I am experiencing this behaviour in 6.0.1.Final and 6.1.0.Beta4, but seems like everything is working as expected in 5.5.0.Final. Is that expected behaviour or a bug? -- View this message in context: http://drools.46999.n3.nabble.com/Activation-group-ignored-when-working-w...
