We changed the namespace from 4.0 to 5.0. If you update the namespace at 
the top, it should now work.

Re: [rules-users] Ruleflows

[Kris Verlaenen]

A RuleFlow simply makes sure your rules are evaluated in a specific order.  
Both strategies are possible, but I believe there are some small differences:
 - If you first insert all your debts and then activate the ruleflow, all 
orders will progress through the ruleflow at the same time (e.g. first apply 
all rules of set1 and then set2).  If you would use separate ruleflows per 
debt, each debt can be handled independently.
 - It will sometimes be harder to identify one specific debt if you insert all 
your debts at once
I think using a separate ruleflow for each of the orders would be the best 
solution here, as each debt can and will be handled independently (you could 
have multiple working memories working in parallel to handle the load).

If you want to make sure only one rule gets activated in a specific ruleflow 
group, you can, as already stated earlier, use an activation group.  This will 
make sure only one of the rules in that activation group will be executed for 
that debt.  You could also manually deactivate the ruleflow-group in the rule 
consequence (using 
drools.getWorkingMemory().getAgenda().deactivateRuleFlowGroup("name")), but I 
would suggest using activation groups if possible (as they are more powerful 
and built for these kinds of things specifically).

  Hi,

  I have to compute the gravity of a debt according to a set of rules organized 
in a ruleflow. I will have to process about ten thousands debts every minute.
  There is no dependency between the debts. All the rules are applied to one 
debt.

  What is the best strategy?

  - Insert all the debts, and start the ruleflow process
   or
  - (Insert one debt, start the ruleflow process) for each debt

  Another question:

  If a rule "r1" in the ruleflow group "rfg1" is fired on a debt "d1", can a 
second rule "r2" in the same ruleflow group be fired on the same debt "d1"?

Re: [rules-users] Ruleflows

[Jeffrey Delong]

Why not try the second strategy you listed below:

- (Insert one debt, start the ruleflow process) for each debt

Since each debt is separate.

As for only firing one rule in the ruleflow group, try using the same 
activation-group attribute on each rule in the ruleflow group. 
Activation groups cause only a single rule in the same group to be 
activated.

I think that I can add an "attribute" in my business object, like 
"boolean gravityComputed" in order to activate only one time a gravity 
compute rule but thats not very clean. Is there any drools action to 
break the deactivate the current flow and activate the next one? and 
if yes, is it possible to call it from a rule?

IMO, the first.
 
Another answer; I believe RuleFlow controls the activation

sequence so IMO "yes". Kris, care to correct me?
