[rules-users] Evaluate rules for multiple facts of the same type within a StateuflSession

[Esteban Aliverti]

Jeremy is right. In the log you can see 2 activations (one for each fact
you insert), then the execution of one of the activations and then
the cancellation of the other. How many rules do you have in your kbase? Is
your rule as simple as the one you posted? Do you have more than just 1
condition in your LHS? Are you doing anything else other than the
system.out in your RHS?

Best Regards,
