I'm using in a rule the 'contains' operator against a Map<String,String>. The method 'containsKey' on Map is invoke twice, first with the key then with the value associated to the key. The rule is evaluated to 'false'. What can I do to prevent this behavior? -- View this message in context: http://drools.46999.n3.nabble.com/Problem-with-contains-tp3463274p3463274...
