[rules-users] Using object.getter in Decision table
Hi, I have a scenario, where for decision table I will inject one object which holds all facts. Using those facts the decision table has rules. How to retrieve the child fact from parent in decision table. sample for this is as follows Java Code snippet: DataObject dataObj = new DataObject(); Fact1 fact1 = new Fact1(); Fact2 fact2 = new Fact2(); dataObj.setFact1(fact1); dataObj.setFact2(fact2); statelessKnowledgeSession.execute(dataObj); In decision table: --- CONDITION fact1 : DataObject().getFact1(); fact1.getData1().equalsIgnoreCase($param) Hello Here I am getting error. Please suggest me how to access the child fact from parent fact in decision table. -- View this message in context: http://drools.46999.n3.nabble.com/Using-object-getter-in-Decision-table-tp3392337p3392337.html Sent from the Drools: User forum mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
Re: [rules-users] Is it possible to retrieve the collection of Conditions from DecisionTable?
If you take a look at the Verifier it goes through the Drools AST with a visitor pattern. It starts by using getting the PackageDescr using DrlParser, this uses Drools internals so be warned that it might change in the future. Reader drlReader = new InputStreamReader( stream ); PackageDescr descr = new DrlParser().parse( drlReader ); After that it goes through the PackageDescr using PackageDescrVisitor. RuleDescrVisitor shows how to get the condition part from each rule. https://github.com/droolsjbpm/drools/blob/master/drools-verifier/src/main/java/org/drools/verifier/visitor/PackageDescrVisitor.java https://github.com/droolsjbpm/drools/blob/master/drools-verifier/src/main/java/org/drools/verifier/visitor/RuleDescrVisitor.java Toni On Oct 3, 2011, at 8:11 PM, Mark Proctor wrote: On 03/10/2011 18:03, Wolfgang Laun wrote: A condition does not have a name, as you write; values of the cells below a condition are (usually) literals.

Re: [rules-users] Using object.getter in Decision table
Why are you using an extra data object -its far easier if your facts are actually facts in the working memory. What you have written as your rules is totally incorrect - you seem to be trying to write java method calls not rule statements. My advice is to a) try writing the same rule as a drl first before trying to represent it in a spreadsheet b) look at the intermediate drl that the spreadsheet compiler produces to get a better understanding of the output that the spreadsheet produces.

Re: [rules-users] Using object.getter in Decision table
The best place to start is the drools documentation http://www.jboss.org/drools/documentation particularly the expert guide. This shows both drl and spreadsheet syntax and examples. You are getting the exception because the first line of the condition should just be an object restriction eg fact1 : DataObject() Your second line is then a restriction on that data object. What you send from your screen and what you insert into the working memory doesn't have to be identical. Your screen may use a single object to relay the object but that doesn't mean you can't explode it into separate facts as you insert it into your working memory, but it depends on what you are trying to achieve - are these just validation rules or are you going to be modifying the objects?

Re: [rules-users] Using object.getter in Decision table
Thomas, The best place to start is the drools documentation http://www.jboss.org/drools/documentation particularly the expert guide. This shows both drl and spreadsheet syntax and examples. - Yes. I have downloaded all the drools info from here. then I got one expert pdf document in reference folder of final distribution. I think it is the same in above URL. Here as mentioned in the document I have defined rules in repository using Guvnor and then tried to access the knowledgebase using knowledgeAgent, which I failed to access from web application where as from console application it is working. You are getting the exception because the first line of the condition should just be an object restriction eg fact1 : DataObject() Your second line is then a restriction on that data object. - that means I can not get the child fact from a parent object as I tried. As of now the only way is I need to insert the facts as and when rule needs it and then retract that. Please correct me If I am missing anything in my understanding. What you send from your screen and what you insert into the working memory doesn't have to be identical. Your screen may use a single object to relay the object but that doesn't mean you can't explode it into separate facts as you insert it into your working memory, but it depends on what you are trying to achieve - are these just validation rules or are you going to be modifying the objects? I am modifying the object, so that based on that object state some functionality has to be done in next layer. what I am trying to achieve is generic rule util methods for my application to use these methods across different method calls.

Re: [rules-users] Looping in When part
You'll need 2 rules, one for truncating a key that does not match and another one for handling the match. If you have to handle absolute failure (not even a matches) you'll need a third rule and a more complex fact for storing the original and the truncated string. These 2 rules are untested: rule truncate when not found when $s: String( length 0 ) $m: Map( keySet not contains $s ) then retract( $s ); insert( $s.substring( 0, $s.length() -1 ); end rule found when $s: String() $m: Map( keySet contains $s ) then System.out.println( key + $s + is in the Map ); end -W On 4 October 2011 15:41, rahulkrishnan rahulkrishn...@gmail.com wrote: Hi I want to match a string with the contents of hashmap.

[rules-users] Are retracted events garbage collected in stateful session?
I am inserting a high volume of relatively large objects into a long-running StatefulKnowledgeSession in Stream mode. I use a rule to start a jbpm process when each event is received, and the last step retracts the event. I assumed these were all being garbage collected until my app server started running out of memory. I ran a profiler and saw that none of my event objects were ever collected. Is there any way of freeing references without disposing the working memory? This is not a good option for our app. I have read this post http://drools.46999.n3.nabble.com/Removing-facts-from-statefulknowledgeSession-s-memory-td1875795.html#a1881799 Removing-facts-from-statefulknowledgeSession-s-memory and several others, but my objects are all manually retracted. I just need to make them available for garbage collection. I am running drools 5.2.0 Final, guvnor 5.2.0 Final, and jbpm 5.1.0 Final and I am using the BusinessRulesProcessor action in jboss to insert events.

Re: [rules-users] 5.3.0 CR1 has broken existing rules/flows
Thanks for all of the feedback. I haven't tried W's handler, but I'm planning to. I did take Edson's advice and was able to get some more info. It appears to involve the interaction between 3 rules. For background, this is a fraud detection application. Under certain conditions, we need to look up additional customer information. Some rules are run to determine whether the lookup is required and then another rule actually does the lookup. In this case: Rule 021 says if the order is small, set the lookup flag to false Rule 042B says if the order is from a 'bad' country, set the lookup flag to true Rule 022 says if the lookup flag is true, do the lookup If rule 021 fires alone, then 022 does not fire and all is well. If rule 042B fires alone, then 022 fires and all is well. If 021 fires to turn off the lookup AND 042B fires to turn on the lookup, then 022 gets and NPE. As Edson suspected, the item is null and the 'rule' variable points to rule 021. I'm not sure if it matters, but each rules involved is in a different agenda group.

The difference in that area from 5.2 to 5.3 is that in 5.3 the interaction between Terminal Nodes and the agenda was refactored into a listerner pattern . This is required for future features we are working on. It seems the change introduced the regression. This is probably enough info to recreate the problem and I bet the different agenda groups are really important in recreating it. I am working in a couple tasks at the moment, but if you can meanwhile open a JIRA with this info I will fix it for the 5.3 final release.
