The code seems fine. Just make sure that your server code matches the client
code and it should work. Really seems like a cache problem (clear browser
cache, clear project, restart development mode, redeploy the application if
you use an external server).

No I mean something like:
public interface MyService extends RemoteService {
public void save(List<String> items);
public List<String> getItems();
}
With such a service GWT will generate Serializer classes for all classes
that implement List (ArrayList, LinkedList, etc) which will increase the
resulting javascript code. So its better to use a concrete implementation of
List, e.g.:
public interface MyService extends RemoteService {
public void save(ArrayList<String> items);
public ArrayList<String> getItems();
}
Its not related to the code you posted here, but I thought it would be a
nice info for you because at some point in your application you may want to
transfer lists of objects between client and server.
