Re: [rules-users] How to get notified just before rule is picked up for evaluation

Hi Ghanshyam, I'm afraid there is no such way. The reason is that Drools does not evaluate rules one by one. A rule can consist of multiple conditions and some of those conditions can be shared by multiple rules (node sharing in RETE network). When you insert a fact into your session, conditions from multiple rules for that fact type are evaluated. So different parts of a rule's conditions may be evaluated at different times during your insert of facts. Only when all conditions for a rule have been evaluated to true an activation is created.

The earliest hook available is DefaultAgendaEventListener . activationCreated(ActivationCreatedEvent event) What I am looking for is to get notified just before a rule is picked up for evaluation and just after it has been evaluated.
