List of strings is not rendered to JSON

Question

I have a domain class

class UserProfile {

    List<String> interests = [];
    ObjectId id;
    String username;
    String password;
    String email;

    static constraints = {

    }
}

which is properly persisted in mongodb by gorm

def user = new UserProfile(username:"name",password:"pass",email:"asd@asd.com",interests: ['women','dogfight']);
user.save()

which could be verified in mongo console:

{ "_id" : ObjectId("528fd78003646357efb421c0"), "email" : "asd@asd.com", "interests" : [ "women", "dogfight"], "password" : "pass", "username" : "name", "version" : 0 }

so i get this object by UserProfile.find() as JSON in controller and got

{"class":"domain.users.UserProfile","id":{"class":"org.bson.types.ObjectId","inc":-273407552,"machine":56910679,"new":false,"time":1385158528000,"timeSecond":1385158528},"email":"asd\u0040asd.com","password":"pass","username":"name"}

as you can see list of interests unfortunately was not rendered

I would appreciate any help. Thanx.

Specifying association in domain class should help.

static hasMany = [interests: String]
