[rules-users] Problem with Java enums in Guvnor "multiple field constraints"?

I've been playing with Drools and Guvnor and think I've encountered a problem with Java enums in Guvnor. I've searched for previous enum bugs and seen that a lot have been fixed, but I've tried Guvnor 5.2.0 and 5.3.0.CR1 and it happens in both. The problem seems to happen when you use enums in a "multiple field constraint" on a fact, eg: There is a Person with: any of the following: role equal to Role.TEACHER role equal to Role.PARENT Then using "view source" to see the generated DRL, the enum values are enclosed in double quotes, ie: rule "test" dialect "mvel" when Person( role == "Role.TEACHER" || role == "Role.PARENT" ) then end If I just do a single field constraint then it comes out fine, eg. Person( role == Role.TEACHER ) Is this a bug or am I doing something stupid? I've seen posts recommending the use of string constants rather than enums - is this the workaround? Below is my simple Java model for completeness: public enum Role { TEACHER, STUDENT, PARENT } public class Person { private String name; private Role role; public Person( String name, Role role ) { this.name = name; this.role = role; } public String getName() { return name; } public Role getRole() { return role; } } -- View this message in context: http://drools.46999.n3.nabble.com/Problem-with-Java-enums-in-Guvnor-multi...
