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.

I've been using agenda groups without any trouble for a similar problem, doing
setFocus( ... );
insert( ... );... insert( ... );
fireAllRules();

You don't have to be afraid of the focus stack growing indefinitely:You control
the "push" (setFocus()), and if an agenda group's activations are all gone, the
group is automatically popped from the stack.
