                 URL: https://jira.jboss.org/browse/JBRULES-2769
             Project: Drools
          Issue Type: Feature Request
      Security Level: Public (Everyone can see)
          Components: drools-core
    Affects Versions: 5.1.1.FINAL
            Reporter: Edson Tirelli
            Assignee: Edson Tirelli
             Fix For: 5.2.0.M1

Create a "transaction"-like context for all WMA to prevent inconsistent states during propagation. The idea is to delay agenda changes (rule activations, cancellations and re-activations) until the whole propagation is finished. This is to avoid inconsistent states when the same fact is propagated through multiple RETE branches.

Examples of cases that require this include: 

* forall re-activating on fact retractions
* fireUntilHalt immediately firing rules that are activated and canceled during the same WMA
