Odd rules execution for expired events
by sopel39
Hi,
I have declared two types:
declare Motion
@role( event )
@expires( 5s )
@timestamp( eventTime )
eventTime : long
end
declare Recording
end
and following rules:
rule "StartRecording"
when
Motion()
not Recording()
then
insert(new Recording())
end
the problem is that when I put a lot of "motions", sleep (so "motions"
become expired) and then do fireAllRules(), I got "StartRecording" executed
multiple times (and not only once), event though Recording is inserted every
time.
It seems that inserting new recording does not cancel expired activations.
Is that correct? How to handle such situation correctly?

Hi ,
I've below rule set up in Guvnor . This rule works fine when other java
application starts up and fetched the rule from Guvnor using knowledge Agent
.
rule "EL-AH-RESTRICT-LOGIN"
no-loop true
dialect "mvel"
when
lcki : LoginChallengeKI( eval( (lcki.getWS_RiskScore() >=
790 && (lcki.getWS_RiskScore() - lcki.getAvgRiskScore()) >= 500) ||
(lcki.getWS_RiskScore() >= 750 && ((lcki.getWS_RiskScore() -
lcki.getWS_RiskScore())/lcki.getWS_RiskScore()) >= 4) ||
(lcki.getWS_RiskScore() >= 750 && lcki.getWS_RiskScore() <= 350 ) ),
userEquityBalance >= 40 , hadPreviousChallenge == false , eval(
!lcki.getValidCookies().contains(lcki.getWS_Cookie()) &&
!lcki.getValidCookies().contains(lcki.getWS_FlashCookie()) ), eval(
lcki.getWS_IPAddr() != lcki.getIpAddr1() && lcki.getWS_IPAddr() !=
lcki.getIpAddr2() ), eval( lcki.getWS_Cookie() != lcki.getCookie1() &&
lcki.getWS_Cookie() != lcki.getCookie2() ), eval( lcki.getWS_FlashCookie()
!= lcki.getFlashCookie1() && lcki.getWS_FlashCookie() !=
lcki.getFlashCookie2() ), eval( lcki.getWS_GeoCity() != lcki.getGeoCity1()
&& lcki.getWS_GeoCity() != lcki.getGeoCity2() ), eval(
CheckAfterHour(lcki.WS_EventTimeStamp) ))
then
lcki.setRuleIDMapValue("ACT03","EL-AH-RESTRICT-LOGIN");
lcki.setChallenge(true);
lcki.setGenerateAlert(true);
end
But if i make any change in the in the guvnor and build the pkg then other
application throws below exception
org.drools.RuntimeDroolsException: Exception executing predicate
(lcki.getWS_RiskScore() >= 790 && (lcki.getWS_RiskScore() -

((lcki.getWS_RiskScore() - lcki.getWS_RiskScore())/lcki.getWS_RiskScore())
>= 4) || (lcki.getWS_RiskScore() >= 750 && lcki.getWS_RiskScore() <= 350 )

Possible to use functions in DRL when dialect is mvel?
by Stephen Masters
Hi folks,
Is it possible to refer to DRL functions from a DRL when the dialect is mvel?
I have been working on unit tests for a rule that were consistently failing due to not being able to find the function that should be imported. Having tried various formats (the documentation is rather unhelpful here) for the import, I thought I'd see what happened if I just switched to the Java dialect. Suddenly it worked without even needing an import statement.
Unfortunately, this forces me to switch from the neat ...
newFact.Property = otherFact.Property
... to the rather ugly Java-style
newFact.setProperty(otherFact.getProperty())
So I would quite like to know if there is an undocumented (or well-hidden-documented) mechanism for using functions when in mvel dialect. Or am I stuck with switching to Java?
Thanks in advance for any pointers anybody can provide,
Steve

Guvnor execution server getting 401 when using AD-configured Guvnor as endpoint
by ndipiazza
We are using:
• Drools Execution Server that came with Drools 5.1
• Drools Guvnor 5.2 configured with active directory
The execution server and guvnor run on the same Tomcat and use the same
port.
With the execution server you can have a listener for each package within
the configuration file. I have two such files, from-file-system.properties
that points to a local directory where a drools binary package is manually
deployed. This works fine.
But I try to use with-guvnor.properties which points to a package binary on
5.3 Guvnor. Here is the file:
I get the following error:
Some sort of authorization error very likely related to the active directory
configuration within Guvnor 5.2.
This used to work for us just fine with an earlier version of Guvnor.
This used to work for us just fine with an earlier version of Guvnor.
How can I fix this issue?

drools planner
by domingo
Hi,
In the cloudbalance example...I noticed two comparator classes...
CloudProcessDifficultyComparator (this is for planning entity class
comparator) and CloudComputerStrengthComparator (this is for planning
variable comparator class),
please help me to understand more about these planning entity difficulty and
planning variable strength comparator classes.
why do we need this and why not use one class level comparator?
thanks,
