Re: [rules-users] Problems with repeated execution of rules

Hello! I have following rules file: import java.util.List; global List outErrorCodes; global Boolean condition1; global Boolean condition2; global Boolean condition3; rule "01" when eval( condition3 == false); then outErrorCodes.add("ERROR_CODE1"); System.out.println("01"); end rule "02" when eval((condition1 == true) && (condition2 == true)); then outErrorCodes.add("ERROR_CODE2"); System.out.println("02"); end When I evaluate this file repeatedly, it is evaluated correctly only the first time. I don't understand why it happens, because I always create a new knowledge base for every execution (I don't re-use sessions). Here is the code: final KnowledgeBase knowledgeBase2 = createKnowledgeBase(getRuleFileNames()); final StatefulKnowledgeSession session2 = knowledgeBase2.newStatefulKnowledgeSession(); ... Then, I set condition1, condition2 and condition3 with calls like this: session2.setGlobal(curName, curValue); curValue is Boolean.TRUE or Boolean.FALSE. Then, I insert the value of the output variable: session2.setGlobal("outErrorCodes", new LinkedList<String>()); Then, I invoke these methods: session2.fireAllRules(); ... session2.dispose(); After fireAllRules, outErrorCodes is always empty (apart from the first run), even in cases, where rule "01" should apply. What am I doing wrong?
