JS Relationship Sharing

I defined 2 schema objects as shown below (for use in mongodb)

var User = describe('User', function () {
    property('name', String);
    property('email', String);
    property('password', String);
    set('restPath', pathTo.users);
});

var Message = describe('Message', function () {
    property('userId', String, { index : true });
    property('content', String);
    property('timesent', Date, { default : Date });
    property('channelid', String);
    set('restPath', pathTo.messages);
});

Message.belongsTo(User, {as: 'author', foreignKey: 'userId'});
User.hasMany(Message, {as: 'messages',  foreignKey: 'userId'});

But I cannot access the related message objects:

action(function show() {
    this.title = 'User show';

    var that = this;
    this.user.messages.build({content:"bob"}).save(function(){
        that.user.messages(function(err,message){
            console.log('Messages:');
            console.log(message);
        });
    });
    // ... snip ...
    }
});

Although a new message has been added to the message collection, the message array is always empty.

I ran db.Message.find({userId:'517240bedd994bef27000001'})through the mongo shell and displayed the messages as you expected, so I'm starting to wonder if there is a problem with the mongo adapter .

One to Many Relationships in CompoundJS Shows a similar problem (I think).

As far as I can work from documents, this should work. What am I doing wrong?

EDIT:

EDIT2: :

action(function create() {
    User.create(req.body.User, function (err, user) {
        respondTo(function (format) {
            format.json(function () {
                if (err) {
                    send({code: 500, error: user && user.errors || err});
                } else {
                    send({code: 200, data: user.toObject()});
                }
            });
            format.html(function () {
                if (err) {
                    flash('error', 'User can not be created');
                    render('new', {
                        user: user,
                        title: 'New user'
                    });
                } else {
                    flash('info', 'User created');
                    redirect(path_to.users);
                }
            });
        });
    });
});
