Hi,

First of all, thank you both for your answers.

@mauricio:
I'm currently not using drools flow, only expert, so i'm not very familiar
with the approach you suggested. Isn't it possible to achieve this goal just
by using drools expert?

@Wolfgang:
My problem is that i cannot have the different rule groups stacked. I may do
as you suggested, but i'll have rules firing from other agenda-groups after
the first agenda-group activations are all gone (because they go into the
stack as well, right?). What i'm looking for is a way to isolate the
execution and just fire the rules within a specific set (aka just one
group). Does this make any sense?

Thank you for your support. I appreciate all the help i can get.
_ miguel
