[rules-users] Problem with sub-process rules inside multiple instances

[Esteban Aliverti]

I'm not sure, but it could be that your rules (which is really just one
rule) belongs to the same rule-flow-group. So, when the first rule node is
executed, the rule-flow-group is activated and the rule get fired. When the
second rule node is executed (in the second iteration of your
multiple-instance), the rule-flow-group is activated again (actually, it was
already active), but since anything has changed since the last execution, no
rules will be fired.
One possible solution could be to add a "guard" restriction to your rules.
So, inside the subprocess you can insert an instance of this "guard" object
before the rule node. You can also even have a rule with low salience to
retract this "guard" when you are done.
