[rules-users] OR with multiple binding in LHS

Hi, I'd like to write a rule that contains an OR condition in the LHS, to match the presence in the working memory of an object with particular values of a specific field. In the rest of LHS, i need to bind other values of the specific object matched. Is there a particular sintax to use for the binding? For example: rule "orCondition" when myObj : (MyObject(field1 == "a") or MyObject(field1 == "b")) //correct column field2: myObj.getField2() // how to correctly get field3: myObj.getField3() // those values? then System.out.println("fields = "+ field2 + field3); Thanks in advance, FC.
