I am from WODM background and have a question on rule flow 1). Why do I need to add all the rules or decision tables to the KnowledgeBuilder object? I have created rule flow with multiple task (rule task # 1 for myRule1.drl, rule task # 2 for myTable.xls). Shouldn’t it take all the elements from the rule task automatically that has been added to the rule flow like WODM does? KnowledgeBuilder builder = KnowledgeBuilderFactory.newKnowledgeBuilder(); DecisionTableConfiguration config = KnowledgeBuilderFactory.newDecisionTableConfiguration(); config.setInputType(DecisionTableInputType.XLS); kbuilder.add(ResourceFactory.newClassPathResource("myRule1.drl",myClas.class), ResourceType.DRL); kbuilder.add(ResourceFactory.newClassPathResource("myTable.xls"),ResourceType.DTABLE, config); kbuilder.add(ResourceFactory.newClassPathResource("myRuleFlow.rf",myClas.class), ResourceType.DRF); 2). Why do I need to give ‘RuleFlowGroup” in my decision table. If I am executing table it should execute all the rows based on their condition? What is the usage of RuleFlowGroup? 3). What is the benefit of using reusable Subtask within rule flow?
