> Key: JBRULES-2881
> URL: https://issues.jboss.org/browse/JBRULES-2881
> Project: Drools
> Issue Type: Bug
> Security Level: Public(Everyone can see)
> Components: drools-core, drools-core (fusion)
> Affects Versions: 5.1.1.FINAL
> Reporter: Wolfgang Laun
> Assignee: Edson Tirelli
> Priority: Critical
> Fix For: 5.2.0.CR1

> A rule combining two events of type A and B, each "seen" through a sliding window of length 1 misfires. Rather that combining the latest A with the latest B, it keeps firing the latest B together with *all* old A's.
> Interestingly, this effect disappears if the order of patterns in the rule is inverted. Given the event sequence: A, A, B, A, B, the
> rule ab when A() over window:length(1) B() over window:length(1) then ... end
> misfires, but
> rule ba when B() over window:length(1) A() over window:length(1) then ... end
> works correctly.
> This may be related to JBRULES-2862.
