Cannot issue fireUntilHalt when using persisted session

by rogerL

Due to an issue with reloading persisted sessions that contained a cron timer rule, I upgraded to 6.1.0.Beta3. Now I'm encountering a problem with a threaded fireUntilHalt command (cannot be issued on a persisted session). Exception in thread "SimpleAsyncTaskExecutor-1" java.lang.UnsupportedOperationException: Command session.fireUntilHalt(); cannot be issued on a persisted session at org.drools.persistence.SingleSessionCommandService$TransactionInterceptor.execute(SingleSessionCommandService.java:474) at org.drools.persistence.SingleSessionCommandService.execute(SingleSessionCommandService.java:353) at org.drools.core.command.impl.CommandBasedStatefulKnowledgeSession.fireUntilHalt(CommandBasedStatefulKnowledgeSession.java:272)... It worked without issue in 6.0.1.Final. Though I suspect not, is this expected behaviour? Alternately, are there configuration/other changes that must be implemented. Libs spring 4.0.1 kie, drools, jbpm 6.1.0.Beta3 hibernate 4.3.4 -- View this message in context: http://drools.46999.n3.nabble.com/Cannot-issue-fireUntilHalt-when-using-p...

Excel Syntax in Decision Tables

by crosbis2

Hi, I have a rule i created in Guvnor which works fine (see below) But i can not create and import the same rule from a decision table. I can not get the syntax to match when i upload the xls and view source. Everything below "when" i have as a Condition Everything below "then" is an Action Line 7: will not import. How do you create empty brackets in excel? Line 9: how do i write this using the pattern / constraint approach in excel? same with Line 11 and 12? Any help would be greatly appreciated. 1. | rule "DecisionA_OptionsAndFutures" 2. | salience 0 3. | dialect "mvel" 4. | when 5. | SCOProduct( productBookingPointId == 1 , productTypeId in ( 4, 5, 20 ) ) 6. | RuleSet( ruleSetName == "SCODecisionPointA" ) 7. | taskTemplates : TaskTemplates( ) 8. | then 9. | TaskTemplate TaskTemplate1 = new TaskTemplate(); 10. | TaskTemplate1.setId( 12038 ); 11. | insert( TaskTemplate1 ); 12. | taskTemplates.addTaskTemplateIfNew( TaskTemplate1 ); 13. | end -- View this message in context: http://drools.46999.n3.nabble.com/Excel-Syntax-in-Decision-Tables-tp40295...

how to create kbases with useful names for JMX

by cjohns13

How can I create new container / knowledgebases so that the names as shown in JMX are not random UUID() strings? Something like this currently: KieContainer container = KieServices.Factory.get().newKieContainer(releaseId); container.newKieSession("myName"); When you enable mbeans via Kie.mbeans.enabled=true Yields, in JMX: objectName: org.drools.kbases:type=2d4ffdab-2aca-4d5d-8c44-a5031c4d4094 but, would rather have it be org.drools.kbases:type=myName How can I create the container/kbase/session so it gets a good name, as it stands now? I can see in KnowledgeBaseFactoryServiceImpl.java that there is a way to set this kbaseId, but can't figure out a way to actually set this at the high level. -- View this message in context: http://drools.46999.n3.nabble.com/how-to-create-kbases-with-useful-names-...

Drools 6 Eclipse debugger does not work?

by Péter Gergely, Horváth

Hi All, I am evaluating Drools 6 for one of our projects but found a strange issue with Eclipse integration; debug functionality does not seem to work at all. Only Rules view displays the rules (which is I believe independent from the debugger) but all of the other views (Agenda, Audit, Global Data, Process Instance, Process Instances, Working Memory) are always empty. I have confirmed that Drools nature is enabled on the project (it is actually the example project generated by the Eclipse plugin) and I start my class as a Drools application in Debug mode. (It is the com.sample.DroolsTest from the plugin-generated sample project) My Eclipse environment is the following: Drools plugin installed: JBoss Drools Core 6.0.0.Final JBoss Drools Guvnor 6.0.0.Final JBoss jBPM Core 6.0.0.Final Eclipse release information: Spring Tool Suite Version: 3.5.1.RELEASE Build Id: 201405030657 Platform: Eclipse Juno SR2 (3.8.2) Version of Drools Runtime is 6.0.1 Final Does anyone have any idea what could be wrong? For me one of the most powerful features of Drools seemed to be its Eclipse-based rule debugging capability. Could someone please help fixing my Eclipse Drools setup? Thanks, Peter

Nested Collect probably

by Chris B

I have a class Employee (name) Certificates (course, year, employee) If the employees have CCNA & CCNP from the “same” year and then if they took “CCIE or J5SE in 2000” or “J4WS in 2001 or 2002, or 2003” The Action should be taken if there are more than 5 such employees. The connection between Employee and Certificates is through Certificates.employee, but I can change it to a list of certificates in Employee also if needed. I start with $e: Employee() Certificate (employee == $e, course == “CCNA”, $ccnaYear : year) Certificate (employee == $e, course == “CCNP”, $ccnpYear : year) //this will get the years for one employee.. //now we need to get all other employees from same year.. //but we still need to make sure all certificates are from the same employee. ArrayList( size >= 2 ) from collect(Certificate ( ((course == “CCNA”, year == $ccnaYear, $e_this:employee) && (course == “CCNP”, year == $ccnpYear, employee == $e_this)) && ( ((course == “CCIE”, year == 2000, employee == $e_this) || (course == J5SE”, year == 2000, employee == $e_this)) || ((course == “J4WS”, year == 2001, employee == $e_this) || (course == “J4WS”, year == 2002, employee == $e_this) || (course == “J4WS”, year == 2003, employee == $e_this)) ) ) This is going crazy at this stage. First problem, - I start with one employee, and try to get his years of CCNA and CCNP Next I am collecting Certificates instead of Employees which I should be collecting and checking the length of the employees. I think something like this will help me http://blog.athico.com/2007/06/chained-from-accumulate-collect.html But I am unable to convert it into my usecase. Please help.

@propertyReactive not work when condition are coded in java

by wtang

I have rule1 and rule2 and rule1 is modifying an object whose property is checked in the when part of rule2 and rule2 should fire. The problem is rule2 is not firing. When I took out the @PropertyReactive annotation, then rule2 will fire. After further investigation, I find the cause is because in the when part I am calling java function to do the comparison as suppose to using native operators like "==". Property Reactive seems to be not working when in the WHEN part of the rules we are calling java function to do the comparison as suppose to using native operators like ==, <, >, etc. Please advice. -- View this message in context: http://drools.46999.n3.nabble.com/propertyReactive-not-work-when-conditio...
