Pedro Almeida commented on DROOLS-1130:
---------------------------------------

[~mfusco], I've been trying to update my version from Drools 5.3.2 to the latest Drools version (6.5.0.Final) and I'm having the same problem as exposed in this issue. On Drools 5, the second rule would trigger, on Drools 6 it does not. If it's not a bug, is it a documented change ? 
Cannot find nothing on this particular subject. Is there a way of triggering the fireAllRules at the end of each timer ?
Thanks.

> I have a DRL file with 2 rules and the first rule has a timer of 3s, after this rule gets fired and a fact is modified, i expect a second rule to get activate and trigger but is not happening. Even though the documentation explicitly said in the 2.9.2 section of:
> http://docs.jboss.org/drools/release/6.3.0.Final/drools-docs/html/ch02.html#d0e1467
> _When the rule engine runs in passive mode (i.e.: using fireAllRules) by default it doesn't fire consequences of timed rules unless fireAllRules isn't invoked again. Now it is possible to change this default behavior by configuring the KieSession with a *TimedRuleExectionOption*_
> Please advise if i have misunderstood the expected behavior, attached is a demo project enclosing the mentioned rules and a testcase.
