Hello, The property change listener advise from the expert doc isn't working for me. http://docs.jboss.org/drools/release/5.5.0.Final/drools-expert-docs/html/... (4.8.3.5) - I've tried setting the configuration KnowledgeBuilderConfiguration config = KnowledgeBuilderFactory.newKnowledgeBuilderConfiguration(); config.setOption(PropertySpecificOption.ALWAYS); KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder(config); - Tried added annotations to Java Class @PropertyReactive, @Modifies - Tried adding @watch to rule FYI: We're using salience but not Agency Groups; also StatelessSession but tried StatefulSesson as well. Any suggestions? Reference to a working code sample would be great. ---------------------------------------------------------------------------- (snippet for creating knowledge base) // Set Property Specific Evaluation KnowledgeBuilderConfiguration config = KnowledgeBuilderFactory.newKnowledgeBuilderConfiguration(); config.setOption(PropertySpecificOption.ALWAYS); //final KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder(); KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder(config); addRulesToKBuilder(ruleFiles, logger, kbuilder); // get the compiled packages (which are serializable) final Collection<KnowledgePackage> pkgs = kbuilder.getKnowledgePackages(); // add the packages to a knowledgebase (deploy the knowledge packages). kbase = KnowledgeBaseFactory.newKnowledgeBase(); kbase.addKnowledgePackages( pkgs ); (snippet for adding rules to KBuilder) for (String ruleFile : ruleFiles) { // this will parse and compile in one step kbuilder.add( ResourceFactory.newClassPathResource(ruleFile), ResourceType.DRL ); if ( kbuilder.hasErrors() ) { logger.error( kbuilder.getErrors().toString() ); throw new RuntimeException( "ERROR: Unable to compile " + ruleFile ); } } (snippet for creating a stateless session) public StatelessKnowledgeSession createStatelessSession(boolean isDebug) { StatelessKnowledgeSession ksession = kbase.newStatelessKnowledgeSession(); if (isDebug) { ksession.addEventListener(new DebugWorkingMemoryEventListener()); ksession.addEventListener(new DebugAgendaEventListener()); ksession.addEventListener(new DebugProcessEventListener()); } return ksession; } (snippet for rule) dialect "java" salience 1350 rule "Initial Normalization: Bid Size - Remove Unwanted Characters" when $md : MarketDataRow ( candidate, hasValue( bidSize ), bidSize not matches "123"//, ) then System.out.println( String.format( "%s; Row %d: '%s';", drools.getRule().getName(), $md.getRowNumber(), $md.getBidSize() ) ); modify( $md ) { setBidSize( "678m" ); } end Thank you in advance, Alex -- View this message in context: http://drools.46999.n3.nabble.com/property-change-listeners-aren-t-workin...

2 things aren't working as expected: 1.) Slot Selection - Rules listening for different properties on the object are being fired ie:) Object obj has 3 properties a, b, and c. Rule 1 modifies obj.a triggers Rule 2 which is listening for obj.b (different property on the same object) Can you please refer me to a working example?
