Explicity mapping between ActionScript and Java objects for the BlazeDS Messaging Service

The BlazeDS documentation shows how to explicitly map between ActionScript and Java objects. For example, this works fine for RPC services, e.g.

import flash.utils.IExternalizable;
import flash.utils.IDataInput;
import flash.utils.IDataOutput;

[Bindable]
[RemoteClass(alias="javaclass.User")]
public class User implements IExternalizable {

    public var id : String;
    public var secret : String;

    public function User() {
    }

    public function readExternal(input : IDataInput) : void {
        id = input.readObject() as String;
    }

    public function writeExternal(output : IDataOutput) : void {
        output.writeObject(id);
    }
}

and

import java.io.Externalizable;
import java.io.IOException;
import java.io.ObjectInput;
import java.io.ObjectOutput;
import java.util.HashSet;
import java.util.Iterator;
import java.util.Set;

public class User implements Externalizable {

    protected String id;
    protected String secret;

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

    public String getSecret() {
        return secret;
    }

    public void setSecret(String secret) {
        this.secret = secret;
    }

    public void readExternal(ObjectInput in) throws IOException,
            ClassNotFoundException {
        id = (String) in.readObject();
    }

    public void writeExternal(ObjectOutput out) throws IOException {
        out.writeObject(id);
    }
}

If I called an RPC service that returns a User, the secret is not sent over the wire.

Is it also possible to do this for the messaging service? That is, if I create a custom messaging adapter and use the function below, can I also prevent secret from being sent?

MessageBroker messageBroker = MessageBroker.getMessageBroker(null);
AsyncMessage message = new AsyncMessage();
message.setDestination("MyMessagingService");
message.setClientId(UUIDUtils.createUUID());
message.setMessageId(UUIDUtils.createUUID());
User user = new User();
user.setId("id");
user.setSecret("secret");
message.setBody(user);
messageBroker.routeMessageToService(message, null);

This should work with Messaging. Another option is to use a BeanProxy (nice example in this here).
