[rules-users] Is there a doc on Guvnor's JCR layout ?
Hie everyone. I'm trying to use Drools 5 with Guvnor. But I'm trying to create a simplified Guvnor-like application tied down to what my particular domain problem is. That is, I'm not going to author my rules myself. I'd rather let that to my end-user whose knowledge upon rules processing is even far from poor... Nevertheless, I'm willing to keep the JCR idea, and I'm striving to produce a repository 100% compatible with Guvnor so I can pick up here and then some functionalities out of Guvnor into my application in a straightforward way. I looked deeply into the Guvnor JCR as well as Guvnor src and I think I have a quite good understanding of what it does. But I don't want to miss anything that could break the compatibility. So is there a detailed documentation on the Guvnor JCR and if so where to grab it ?

Guvnor uses Apache Jackrabbit for persistence. You can find a pretty good walk through on the Drools blog http://blog.athico.com/2008/08/tuning-guvnor.html. Additional information about configuring the repository can be found on the Apache Jackrabbit site. http://jackrabbit.apache.org/jackrabbit-configuration.html 2) How do you use the test scenarios with complex object structures? -eg Create a fact in working memory that has another Object in it which in turn has a list of Objects in it. -Seems like any Fact in working memory is assumed to only have only primitive values like Strings or numbers. -We would like a more depth of objects where objects have a deep relationship to other objects at least 2-4 levels deep.

If the ruleflow-group is part of the rule then you can't use the same rule in multiple ruleflow-groups and leads to copy and maintaining the rule in two different spots.

Maybe ask the dev group this one also. 5) Is Java 5 Type Enumerations supported? I was assuming I'd get a list of values if a field was an Enumeration. Not sure 6) There seems to be a vast functionality difference between the Guvnor decision tables and examples that use spreadsheets. I believe that Guvnor decision tables are not as full featured as the spreadsheet based version, but you can still upload spreadsheets to Guvnor as decision tables. 7) Guvnor lost the ability to select variables for use in other statements. Functionality was in BRMS of drools 4.0.7 I don't understand the question. Are you talking about assigning a pattern or an attribute in a pattern to a variable for use in another statement in the LHS or RHS? If so clicking on the fact type or field restriction that gives you that option. 8) I was not able to insert a fact using a constructor that needed parameter values. Seems like it assumes everything is a bean but I couldn't find this requirement stated in the documentation anywhere. Examples in documentation show inserting facts with constructor parameters. Are you talking about in the Guided Rules Editor? I haven't tried this, but it sounds like a bug. Maybe ask the dev team. 9) It would be nice when you upload a domain model jar that you could explore the objects and fields somehow. I agree, being able to traverse the model that you include would be nice. Maybe ask the dev team if there are plans for such a feature or create a request in the Guvnor JIRA. https://jira.jboss.org/jira/browse/JBRULES 10) When you write a rule using one particular editor it would be nice if you could switch to another editor. Switch between Guided, DSL, Technical, etc. Agreed. Some other posters on the email group have discussed this before. As it stands the different editors aren't equally as powerful. Some rules can not be represented in the Guided editor since it does not have anything capable of from (I think). Maybe ask the dev team about this and possibly create a feature request. 11) It seems hard to reorder the statements in a when or then block. If I put them in the wrong order I have to delete them

To keep the example accessible to everyone, and at the same time keeping things a bit more fun, I dropped the idea of developing a business application and decided to go with a board game implementation, so that at the same time it is easy enough for people to understand but complex enough to demonstrate the engine features. At this point, I have a bit more than 50 rules already implemented for this example, it uses drools flow, custom evaluators and custom accumulate functions. I will still add work items, DSL and fusion features. In the end, I estimate the example will have between 120 and 150 rules, what is pretty decent for an example, I think.

RE: [rules-users] RE: questions on guvnor and drools 5.0
We have lists of objects and I was talking about how you do it with the test scenario in Guvnor. The fact is in working memory but I need to be able to create the object so it has a list of objects. Because the rule matches if it is in working memory and party of another object's list. So if I have a School and Children for example Then I write a rule that says if School and Child where child is a member of the School [when] $child : Child(readyForRegistration == true) $school : School($child memberof children) [then] $school.registerChild($child); [end] So in Guvnor I need to create a test scenario where School has a list of Children objects. But Guvnor only shows me a textfield so I assume it wants a value like Bob or 1. I don't see the option or an example how to create a Child fact with a name of Bob and readyForRegistration = true. Then another child with name of Nancy which readyForRegistration = false. Then I want to put them in both into a collection and create a new School object using the collection of Bob and Nancy. I can do this type of thing easily with a JUnit test creating and inserting facts into working memory. It would be nice if business users could write test scenarios just as easy with Guvnor. If you haven't checked out that part of Guvnor it might help if you take a peek.

[rules-users] Why are MVEL rules compiled on first access?

We use the BRMS to compile the rules from drl files (using java dialect) into rule packages which are updated into the rule base using the rule agent. We have seen that MVEL rules are compiled when the rules are fired for the first time. If the fact passed at the first run contains a Hibernate proxy (subclass of the original object) and we later re-use the compiled rule on the fact containing the original object, we get a ClassCastException. However, if we pass the fact containing the original object in the first run, there is no problem for further runs. Why are the rules not compiled when we create the package using the BRMS?

How would I create a constraint rule to match this? I guess the bigger question here is, how do I access the process scope request variable in the constraint?

However, if we pass the fact containing the original object in the first run, there is no problem for further runs. Why are the rules not compiled when we create the package using the BRMS? How can we enable precompilation so that the type is taken as the original object itself?

[rules-users] Default rule
Anyone knows if it is possible to have a `default` rule that would fire only if others have not? Also, is there a way, using decision tables in XLS, to look if the value of a field is contained in a list elsewhere in the XLS? Thanks André ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
Re: [rules-users] Default rule
How about if you create a rule with lowest salience, this will fire _after_ all other rules have fired. Would this help?

RE: [rules-users] Default rule
Yes, but I will have to have a condition in that rule to prevent it from firing if others have. I will have to alter my data model to detect that situation. I can fix my problem using the salience parameter but I was wondering if there is was a built-in mechanism for that purpose. I will try with the salience method Thanks -Original Message- From: rules-users-boun...@lists.jboss.org [mailto:rules-users-boun...@lists.jboss.org] On Behalf Of Ingomar Otter Sent: Thursday, June 04, 2009 4:28 PM To: Rules Users List Subject: Re: [rules-users] Default rule How about if you create a rule with lowest salience, this will fire _after_ all other rules have fired.

[rules-users] Timer does not return!
I have a timer in my code that does not return. It just hangs the process (with
no CPU activity).
Any idea what may be causing this?
The timer delay is 2000 ms. Based on the docs, here are code snippets:
...
ksession = kbase.newStatefulKnowledgeSession();
new Thread(new Runnable() {
public void run() {
ksession.fireUntilHalt();
}
}).start();
final RFQRequest req = createRequest();
parameters.put(rfqIn, req);
ksession.setGlobal(reqTag, req.getTag());
ksession.startProcess(com.rbs.gbm.pm.RFQ-WorkFlow, parameters);
If I remove the fireUntilHalt thread, the timer is not triggered at all. The
flow just passes through it lilke its not even there.
Any help / info / pointers will be appreciated.
Thanks
Ajay
