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.

What could be wrong?
