Hello, If I have a complex rule with a few conditions concatenated via AND and OR and NOT, and the rule evaluated to true during the engine run - is there a way to figure out which of the conditions caused the rule to evaluate to true? In a simple example: rule "test1" dialect "java" when $data : ContractRulesData (region=='NE' && sum > 250) then approverList.add("approver1, approver2, Level1"); System.out.println("test1 is TRUE; result: approver1, approver2, Level1"); end I tried to add an AgendaListener with the following code to find out which rules have fired: public void afterActivationFired(AfterActivationFiredEvent event, WorkingMemory workingMemory) { Activation activation = event.getActivation(); Rule rule = activation.getRule(); GroupElement[] leftElements = rule.getTransformedLhs(); System.out.println("afterActivationFired: rule = " + rule.getName()); System.out.println("Conditions: "); for (GroupElement left_el: leftElements){ System.out.println(left_el.toString()); } The output is somewhat cryptic : afterActivationFired: rule = test1 Conditions: AND[Pattern type='[ClassObjectType class=com.emptoris.ecm.domain.ContractRulesData]', index='0', offset='0', identifer='[Declaration: type=ValueType = 'Object' identifier=$data]'] So, is there a way to get even more information about the conditions and whether they evaluated to TRUE or FALSE? Thanks, Marina
