No, that’s not it.  Using “1.0” causes the exact same syntax error.

Maybe because the 1.0 is in single quotes, and not double quotes, like the others?

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?
