[rules-users] Problem with updated facts

[thomas moncieu]

Excuse me for losing the beginning of the thread, I'm a new user of this
mailing list ...
I solved my problem in separating my ruleflow in two because some rules
should be fired many times and so no-loop was not the solution I needed.

So I do the following thing :

            workingMemory.startProcess("RG_A");
            workingMemory.fireAllRules();
            FactHandle f = workingMemory.getFactHandle(_bill);
            workingMemory.update(f, _bill);
            workingMemory.startProcess("RG_T");
            workingMemory.fireAllRules();
            workingMemory.dispose();

Is lock-on-active efficient only in a ruleflow-group or for all the rules ?
