[rules-users] refactoring "complex" conditon to use "in" operator

Hi, The following rule is working well. rule "foo" when Message(_initialStubRate == "1.0") || Message(_initialStubRate == "2.0") || ( Message(_initialStubRate >= "4.0") && Message(_initialStubRate <= "44.0") ) || Message(_initialStubRate == "52.0") then System.out.println("foo"); End To make this logic more amenable to being generically rendered via .DRT template, I want to simplify this rule . Consider the following re-factoring. rule "bar" when Message(_initialStubRate in ( '1.0',"2.0", "4.0","5.0","6.0","7.0","8.0","9.0","10.0", "11.0", "12.0","13.0", "14.0","15.0","16.0","17.0","18.0","19.0","20.0", "21.0", "22.0","23.0", "24.0","25.0","26.0","27.0","28.0","29.0","30.0", "31.0", "32.0","33.0", "34.0","35.0","36.0","37.0","38.0","39.0","40.0", "41.0", "42.0","43.0", "44.0", "52.0") ) then System.out.println("bar"); end This re-facotred rule produces a syntax error in Eclipse's .DRL view.
