Re: [rules-users] lock-on-active, why keeps evaluating?

Here is an example from the eclipse basic test project, i have added a new Rule allways to be fired with lock-on-active true and also added a function to make a printiln in the console to see what gets evaluated. Code to run: package com.sample; import org.drools.KnowledgeBase; import org.drools.KnowledgeBaseFactory; import org.drools.builder.KnowledgeBuilder; import org.drools.builder.KnowledgeBuilderError; import org.drools.builder.KnowledgeBuilderErrors; import org.drools.builder.KnowledgeBuilderFactory; import org.drools.builder.ResourceType; import org.drools.io.ResourceFactory; import org.drools.logger.KnowledgeRuntimeLogger; import org.drools.logger.KnowledgeRuntimeLoggerFactory; import org.drools.runtime.StatefulKnowledgeSession; /** * This is a sample class to launch a rule. */ public class DroolsTest { public static final void main(String[] args) { try { // load up the knowledge base KnowledgeBase kbase = readKnowledgeBase(); StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession(); KnowledgeRuntimeLogger logger = KnowledgeRuntimeLoggerFactory.newFileLogger(ksession, "test"); // go ! Message message = new Message(); message.setMessage("Hello World"); message.setStatus(Message.HELLO); ksession.insert(message); ksession.fireAllRules(); logger.close(); } catch (Throwable t) { t.printStackTrace(); } } private static KnowledgeBase readKnowledgeBase() throws Exception { KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder(); kbuilder.add(ResourceFactory.newClassPathResource("Sample.drl"), ResourceType.DRL); KnowledgeBuilderErrors errors = kbuilder.getErrors(); if (errors.size() > 0) { for (KnowledgeBuilderError error: errors) { System.err.println(error); } throw new IllegalArgumentException("Could not parse knowledge."); } KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase(); kbase.addKnowledgePackages(kbuilder.getKnowledgePackages()); return kbase; } public static class Message { public static final int HELLO = 0; public static final int GOODBYE = 1; private String message; private int status; public String getMessage() { return this.message; } public void setMessage(String message) { this.message = message; } public int getStatus() { return this.status; } public void setStatus(int status) { this.status = status; } } } Rules file: package com.sample import com.sample.DroolsTest.Message; function boolean testEval(String arg) { System.out.println(arg); return true; } rule "Hello World" when eval(testEval("Hello World eval up")) m : Message( status == Message.HELLO, myMessage : message ) eval(testEval("Hello World eval down ")) then System.out.println( myMessage ); m.setMessage( "Goodbye cruel world" ); m.setStatus( Message.GOODBYE ); update( m ); end rule "Allways" lock-on-active true when eval(testEval("Allways eval up")) Message() eval(testEval("Allways eval down")) then System.out.println("Allways has run"); end rule "GoodBye" when eval(testEval("GoodBye eval up")) Message( status == Message.GOODBYE, myMessage : message ) eval(testEval("GoodBye eval down")) then System.out.println( myMessage ); end Out put: Hello World eval up Hello World eval down Allways eval up Allways eval down GoodBye eval up Allways has run Hello World GoodBye eval down Allways eval down Goodbye cruel world Why the rules Allways has been evaluated again after been fired, for what i understand if the rule has lock-on-active true It shouldnt be evaluated again since it shouldnt run any more. -- View this message in context: http://drools-java-rules-engine.46999.n3.nabble.com/lock-on-active-why-ke...
