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

Subject: [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.
