Re: [rules-users] firing rules twice in single session on single object

let me clear this by following code public static void main(String[] args){ KnowledgeBase knowledgeBase = createKnowledgeBase(); ArrayList<SalesAmount> testSalesAmounts= getSalesAmount(); StatefulKnowledgeSession session = knowledgeBase.newStatefulKnowledgeSession(); for(SalesAmount eachSalesAmount: testSalesAmounts){ session.insert(eachSalesAmount); session.fireAllRules(); } } public static ArrayList<SalesAmount> getTestSalesAmounts(){ ArrayList<SalesAmount> testSalesAmount = new ArrayList<SalesAmount>(); for(int i =0; i<15;i++){ Random random = new Random(); SalesAmount.testSalesAmount= new SalesAmount(); testSalesAmount.setId(i); testSalesAmount.setSalesAmount(random.nextInt(500)); testSalesAmounts.add(testSalesAmount); } return testSalesAmounts; } SalesAmounts is assigned randomly using util class and each fact is inserted at a time in the loop control if after the loop , the data changes how can i fire the rules please modify my code if any mistakes you find........ regards sai On Fri, Oct 12, 2012 at 2:05 PM, abhinay_agarwal < abhinay_agarwal(a)infosys.com&gt; wrote:
