[jboss-jira] [JBoss JIRA] Assigned: (JBRULES-2719) Count in accumulate behaves incorrect in combination with update

Count in accumulate behaves incorrect in combination with update ---------------------------------------------------------------- Key: JBRULES-2719 URL: https://jira.jboss.org/browse/JBRULES-2719 Project: Drools Issue Type: Bug Security Level: Public(Everyone can see) Affects Versions: 5.1.1.FINAL Reporter: Wouter Horré Assignee: Edson Tirelli Attachments: count.zip The following rule produces different results when update is used in contrast to when retract/insert is used (when a Container instance has changed): rule "Count With Accumulate" when $l : Leaf(); Number($nb: intValue) from accumulate($c : Container(leafs contains $l), count($c)); then System.out.println("Leaf " + $l.getName() + " with accumulate: " + $nb); end The following rule produces the correct result in both cases: rule "Count With Collect" when $l : Leaf(); HashSet($nb : size) from collect(Container(leafs contains $l)); then System.out.println("Leaf " + $l.getName() + " with collect: " + $nb); end I have attached a minimal example that triggers the behavior.
