Cast test apparently switches types.

Question

I'm having a strange casting problem when using livecycle and flex client classes.
My setup is something like this:
at the server side:
<destination id="service">
  <properties>
    <server>
      <actionscript-class>ServiceImpl</actionscript-class>
    </server>
  </properties>
</destination>
at the client side:
public interface IService {
  function get name () : String;
  function set name (name :  String) : void;
[Managed]
[RemoteClass]
public class ServiceImpl implements IService {
  public var serviceName : String;
  public function get name () : String {
    return name;
  public function set name (name : String) : void {
    this.serviceName = name;
<mx:ComboBox id="serviceComboBox" dataProvider="{services}" labelField="name" enabled="false"/>
Now I would expect the returned object to be of class ServiceImpl.  But apparently the labelField here doesn't exist on the object.  The object is also show in the debugger as Object@... so I guess it's a dynamic object.  First I thought this was an error on the display of the debugger but it's getting a little bit weird.  With serviceName as labelField this does work and when I put a cast test on ServiceImpl the labelField name suddenly does exist on the object.  Anyone any idea why this behaviour occurs?
