Below is the source code of the enum, entity and radioButtonGroup component.

if value is Male in database and we access the records we get class cast exception

----Class 1 —

public enum UserTableGender implements EnumClass<String> {
    Male("Male"),
    Female("Female");

    private String id;

    UserTableGender(String value) {
        this.id = value;
    }

    public String getId() {
        return id;
    }
    @Nullable
    public static UserTableGender fromId(String id) {
        for (UserTableGender at : UserTableGender.values()) {
            if (at.getId().equals(id)) {
                return at;
            }
        }
        return null;
    }
}

---------------------Class 2 ---------------

public class UserTable {
@Column(name = "GENDER")
    private String gender;

public String getGender() {
        return gender;
    }
    public void setGender(String gender) {
        this.gender = gender;
    }
}

The entity getter and setter must be of the enum type (UserTableGender).
See Enumerations :: Jmix Documentation.
