All, For the next Drools release we intend to add support to event abstraction, event sequencing, pattern repetition and related features. A draft proposal can be found in the following link: https://community.jboss.org/wiki/EventSequencing I opened a JIRA to centralize feedback for future reference: https://issues.jboss.org/browse/JBRULES-3514 Feedback is welcome on the above ticket. I would like to minimize e-mail feedback as that ends up lost in time. Individual features will be implemented in sub-tickets of the above master ticket. I am starting to refine the draft and will start the design asap, so the sooner you send me feedback, the more likely it will be included in the final release.
