Manners Benchmark broken!?

Hello drools-community,
I tried to run Manners Benchmark test and got this error message:

Fusion 5.5 - Deterministically identifying event insert order?
by dunnlow
I am testing with fusion (5.5) and running into an /intermittent /issue. I
am trying to track transitions between two big events (BEvent) using a
smaller event (SEvents) with the properties I care about. The idea is that
I will maintain many SEvents in memory for the different kinds of BEvents.
My basic steps (partly driven by salience) are:
1) rule a: (salience=100): when a new BEvent is inserted, insert a new
related SEvent
2) rule b: (salience=50): If there are two SEvents for this type of BEvent,
compare them (old vs new) and act accordingly
3) rule c: (salience=0) remove the *old* SEvent (keeping the latest one)
4) rule d: (salience=-50) retract the BEvent
My rule c (above) is:
when $se1 : SEvent(name matches "auto")
$se2 : SEvent(this after $se1, style matches ($se1.style))
then
retract($se1);
end;
I am of course running in stream mode and this USUALLY works, but sometimes
rule c does not get activated - based on the audit log. Also, I have a
DebugWorkingMemoryEventListener configured and I can see that two SEvents DO
exist in working memory which should activate it.
In my test, I have a loop in which I am inserting events. When I add a
brief delay, I have not seen a failure. My guess is that the timestamps on
the two events are the same, thus the "after" is causing the issue.
However, I am unable to test this as the timestamp on the event is not
accessible (from what I have found on this forum).
I saw a suggestion here about using a variable on my SEvent to tell the
difference between a new and old version. I also considered using some sort
of counter bean to order the SEvents (although I believe it would need to be
serialized).
My questions:
1) Do you agree with my assessment? Is it possible in stream mode to have
two events with the same timestamp?
2) what is the BEST way to identify which event was inserted first?
Thanks for any insight!

Reg : Drools 5.5 Templates : CompoundValueRestrictions
by Barada (Native5)
Hi,
Am trying to model some rules using drools templates.
Currently the data inputs to rule templates are only strings, I need to be able to define a compound value restriction set for the rule i.e if fact attribute is present in a list. (see sample below).
e.g.
template header
dealers
template "my-template"
rule "my-rule"
when
$order : Order(dealer in (@{dealers}))
then
System.out.println("Order is present in dealer"
end
end template
I am trying to compile this template by passing it an Object which has a dealers attribute which is essentially a List<String>. Short of creating a function which sends back a comma separated representation of the list, does the drools compiler provide any option to send a list.

NullPointer while deleting a rule since 6.0.0 upgrade

Hey,
I recently upgraded drools from 5.5.0.Final to 6.0.0.CR3
A rule deletion that used to work now throws a NullPointerException.
A fact has to be inserted for the Exception to be thrown.

Hi,
I want to know that is there any configuration in Guvnor to limit the number of unsuccessful login attempts. This is required as I want to prevent Brute Force attack on my production Guvnor server.
Environment:
1. Drools-Guvnor 5.5.0-Final
2. Jboss EAP 6.1.0
Thanks and Best Regards,

How To Implement Rule Flow
by neerajs20
Hi All,
I am new to drools and guvnor. I have basic question for rule flow.
I have created 3 rules using guided editor on guvnor plugin. Now I want to
invoke the 2nd or 3rd rule based on the outcome of 1st rule.
e.g. If the patient's age is less than 18 go for 2nd rule for minor checks
otherwise invoke 3rd rule for check from senior physician.
So can this be achieved using rule flow? If yes how? Is there any example
links, documents demonstrating it? Any help very much appreciated.
Thanks

Optaplanner rules error
by SNELS Nick
Hi,
I have the following Drools rule in Optaplanner:
rule "oneShiftPerDay"
when
$leftAssignment : ShiftAssignment($leftId : id, $employee : employee, $shiftDate : shiftDate, employee != null)
$rightAssignment : ShiftAssignment(employee == $employee, shiftDate == $shiftDate, id > $leftId)
then
scoreHolder.addHardConstraintMatch(kcontext, -1);
end
But when I run the solver I get the following error:

performance of ruleflowGroup
by ashish6276
Hi
I am exploring ruleflow. Can somebody help me in knowing how
RuleFlOWGROUP affects the performance of rules. Say i have 1 lakh rules.
what will be difference in performance if i keep all rules without any group
and if i group rules in diff small small ruleflowgroup and then create a
processflow to execute the flow in such a way where selected ruleflowgroup
will be used based on condition defined in process flow.
