Hi, I created the below mentioned rules: 1. Two rules with same when and then conditions using a business guided editor. 2. Two rules with contradicting WHEN conditions. In the above mentioned scenarios how can we check the rules are contradicting and they are duplicate. I tried package analyzer in guvnor. But i did not get much information from that. Please help me how to detect duplicate and contradicting rules. -- View this message in context: http://drools.46999.n3.nabble.com/How-to-check-duplicate-and-conflicting-...
