How to make BlazeDS ignore properties?

Question

I have a java class which has one field with getter and setter, and a second pair of getter and setter that access this field in another way:

public class NullAbleId {
   private static final int NULL_ID = -1;
   private int internalId;

   getter & setter for internalId

   public  Integer getId() {
     if(this.internalId == NULL_ID) {
       return null;      
     } else {
       return Integer.valueOf(internalId);
     }
    }

    public void setId(Integer id) {
      if (id == null) {
        this.internalId = NULL_ID;
      } else {
        this.internalId = id.intValue();
      }
    }

}

(the reason for this construction is that I want to build a way to hande Nullable Intergers)

On the Flash/Flex client side, I have a Class with two properties: id and internalId (the id properties are only for testing, at the end they should return the internalId value)

BlazeDS seams to transfer both values: id and internalId, because both have a complete getter setter pair. I want Blaze not to transfer id, only internalId should be transferred. But I have no idea how I have to configure that.

Besides transient / marshaller you can implement the Externalizable interface and create your custom serialization.
