[rules-users] enums and subclass under guvnor : no listbox

Hi all I have two simple classes : The parent class has a field that is an enum. The other class inherits from the parent class. Under Guvnor, everything is OK for the parent class : when I add a constraint on the "enum" field, I see a listbox with enum values But for sub-class, the same field has no listbox, but only a free value text input. Can you confirm this is a bug? I use Guvnor 5.2.Final. Thanks ! The code : public enum Status {     OK , KO , UNKNOWN ; } public class MotherClass {     private Status status ; // and corresponding get/set enum Status {     OK , KO , UNKNOWN ; } public class MotherClass {     private Status status ; // and corresponding get/set     OK , KO , UNKNOWN ; } public class MotherClass {     private Status status ; // and corresponding get/set public class MotherClass {     private Status status ; // and corresponding get/set     private Status status ; // and corresponding get/set } public class SubClass extends MotherClass {     private String message ; // and corresponding get/set } class SubClass extends MotherClass {     private String message ; // and corresponding get/set }     private String message ; // and corresponding get/set }
