[rules-users] are activated working sets persisted?
Hi all, here is my question: are activated working sets persisted in drools repository? In my guvnor instance, logging out from current browsing session does reset activated working sets for my rules.. Is this intended? Guvnor user manual says real-time validation is not persisted, so I guess the same apply on activated working sets. Thanks in advance!

[rules-users] Enumerations for nested classes
Hi all, I have a problem with data enumeration for nested classes in BRLs. I have two classes, Promotion and Program. Promotion has a property named "program" of type Program, which has a string property called "code". I did a couple of enumeration in this way: [Program.code] = ['ABC=First Program','XYZ=Second Program'] [Promotion.program.code] = ['ABC=First Program','XYZ=Second Program'] With decision table they work as expected, but in BRL rules only the first works (the one with no nested classes), while in the other case the drop-down list doesn't appear and it's shown only a free editable field. How can it be? Should I write something in a different way? Is it a bug? I'm using version 5.2.

[rules-users] Setting category tags programmatically
Hi all, my application needs several hundreds rules to implement its business logic. We generated such rules from a legacy database using a few sql scripts, since the relevant tables contained the business configuration constraints for the app, and then added them to Guvnor by means of the eclipse plugin. Is it possible to set category tags programmatically for that rules artifacts in Guvnor? Possibly a script or some java api?

Re: [rules-users] Eclipse Java compliance
Figured out the problem: I let my default eclipse.ini, so that it was picking up a default java vm from my program files, more specifically a java 1.5 vm. Just added -vm option (and right path to 1.6 vm) to my ini file and it solved the problem. I can't understand why I had no problems in all my projects, but only on drools rules. Hope this helps.

Re: [rules-users] looking for more information on drools expert
Thank you very much for the precision, I didn't see that. I used 'matches' instead of '==', because using '==' for comparing Strings in java is very unsafe since it compares the references and not the content of the strings. I thought it was the same in drools and I thought 'matches' was the equivalent of the java '.equals' method. But now you mention that in drools '==' is correct, I will use it rather.

Re: [rules-users] looking for more information on drools expert
I finally suceeded to get what I wanted using the keyword accumulate which is really very poweful as said in the doc. Here is the rule: http://drools.pastebin.com/m4f938e40 It is a little bit complex, but it perfectly works. The only observation I have is that it seems drools compatible jdk is < 1.5, since I tryed to declare my linkedlist this way: LinkedList(), but got warnings about the unexpected '<'. One other thing, the "implicit and" does not work in the accumulate, you have to put it clearly. Now I have something giving me the list I need, all should be easy I think. Do you have any observation on the way I did it? Cheers Aldian ___ rules-users mailing list rules-users@lists.jboss.org http://lists.jboss.org/mailman/listinfo/rules-users

As for the alarms that have been correlated in only one, I don't know how they are dealt with commonly, but here are the problems we have seen: 1) In the hypothesis where a same single alarm could be correlated with different pairs to create correlated alarms in different cases, it would be careless to retract it after having been correlated one time, because it would block all further correlation 2) In the hypothesis where a correlated alarm sum of a lot of single one has been created and where an event is raised to tell that one of these alarms has fallen: Two possibilities: Introducing the notion of "correlated alarm partially cleared" or removing the correlated alarm and reintroducing its remaining components. If the correlation has been well done, it doesn't make sense to use the first possibility, because once the condition are no longer validated, there is no reason to display the correlated alarm any further. Here is the way we will deal with this: Currently there are two list of alarms in main class: a) the list of alarms that has been inserted to drools (including single and correlated ones) but not cleared yet b) the list of alarms that should be displayed to the operator. So basically, when we decide that a group of alarms should be correlated in only one, we remove them from the list (b) and we add to (a) and (b) a correlated one that contains all the group. When an event rise to signal that one alarm is no longer raised, all correlated alarms it is part of are destroyed and removed from both lists and all their components except the fallen one are re-added to list b. The mechanisms allowing this are based on the alarm keys that are unique and on some mappings. So as you see there is a distinction between what is in drools, and what is visible by the operator. All non cleared alarms (single and correlated) are permanently in drools until it is destroyed because it has been cleared. The only inconvenient is then to avoid the rules to fire indefinitely, since they are permanently susceptible to be validated. To avoid this all rules are of type "If some alarms respect the folowing conditions and at least one of them is not part of a correlated alarm built for this rule, then...". There are probably smarter ways to do, but this is my point of view for the moment.

[rules-users] ascendant compatibility drools 4.0 <-> drools 2.0 ?
Hi everybody Short presentation since this is my first time posting there. I am a french engineering student at the end of his studies, and I am currently working as a trainee on a project where I have to make a lot of software working together. I am currently studying a way to correlate alarms sent by a lot of equipements from a network (type NMS), using openOSS' correlation module, which was using drools 2.0 beta 2.1 But since it seems the current stable version is drools 4.0, I am thinkint about using it instead. But if I do so, I will have to bother about ascendant compability. The programm from openOSS is using drools through JSR94 interface. Do you think there will be any problem? Where can I find a good page relating major changes in drools since drools 2.0? Other question: my project is really ambitious, and I plan to use rules which will adapt to the topology of the network. Depending on what is possible in drools, I am thinking about creating a program which will use a file containing static rules and another one containing the topology of the network to remotely generate new rules each time I change the network topology. But maybe this dynamic rule generation is already available in drools? What do you think?
