Steve McDowell commented on JBRULES-1428:
-----------------------------------------
I get this problem too. Here is the drools
rule "Under 30s"
when
$person : Person( age < 100 )
then
System.out.println("Person " + $person.getName() + " is under 100");
end
And here is the Java
public class Person {
private BigDecimal age;
public BigDecimal getAge() {return age;}
public void setAge(BigDecimal age) {this.age = age;}
private String name;
public String getName() {return name;}
public void setName(String name) {this.name = name;}

----------------------------------------
OK I can see this in both trunk and 4.0.4 - yes the rework done on the evaluators has
broken how it handles literal values. Will need to think of best way to fix this.
