GWT Restlet Parameters Always Null

Question

I am brand new to both REST and RESTlet- I got everything up and communicating last night but what I found this morning is that everything I pass into the server is always becoming null.

just as a sample app i have the following - a User Objectify entity (id, emailAddress, and version), and a RESTUserProxy object (id, emailAddress) - I wasn't originally sure if i could pass Objectify Entities back and after not being able to see anything switched it to the Proxy object - if i can get it to work this way I will try switching it back

the front end is as follows:

public interface RESTUserResourceProxy extends ClientProxy {

  @Get
  public void find(String emailAddress, Result<RESTUserProxy> callback);

  @Put
  public void persist(RESTUserProxy user, Result<Void> callback);

  @Delete
  public void delete(RESTUserProxy user, Result<Void> callback);
}

the backend code is as follows (this is currently extremely ugly - i got a little frustrated just trying to see something and put in a ton of sysouts)

public class RESTUserServerResource extends ServerResource implements RESTUserResource {

  private final UserDao userDao;

  public RESTUserServerResource() {
    System.out.println("CREATED USER RESOURCE IMPL");
    userDao = new UserDao();
  }

  @Override
  @Get
  public RESTUserProxy find() {
    System.out.println("reference = " + getReference());
    Form queryParams = getReference().getQueryAsForm();
    System.out.println("query params = " + queryParams);
    System.out.println("query = " + getQuery());
    System.out.println("query string = " + getQuery().getQueryString());
    String searchQuery = (String) getRequest().getAttributes().get("searchQuery");
    System.out.println("search query = " + searchQuery) ;
    return null;
//    if (emailAddress == null) {
//      return null;
//    }
//    System.out.println("user resource impl find [" + emailAddress + "]");
//    final User user = userDao.find(emailAddress.getText());
//    if (user != null) {
//      System.out.println("found user ");
//      return new RESTUserProxy(user.getId(), user.getEmailAddress());
//    } else {
//      System.out.println("found absolutely nothing");
//      return null;
//    }
  }

  @Override
  @Put
  public void persist(RESTUserProxy userProxy) {
    System.out.println("user proxy = " + userProxy);
    if (userProxy == null) {
      return;
    }
    final User user = userDao.find(userProxy.getId());
    user.setEmailAddress(userProxy.getEmailAddress());
    user.setId(userProxy.getId());
    userDao.persist(user);
  }

  @Override
  @Delete
  public void delete(RESTUserProxy userProxy) {
    final User user = userDao.find(userProxy.getId());
    userDao.delete(user);
  }
}

what im having problems with is that eerythings coming through as null - a lot of other answers on here said to get the query to get the params - but here the query is null

below is the output of calling find and persist

reference = http://127.0.0.1:8888/users/123
query params = []
query = []
query string = 
search query = null

i'm sure i'm doing something stupid here i just have no idea how to proceed right now. Any help as to what i'm doing wrong would be greatly appreciated.

This is due to GAE not supporting chunked encoding. See workaround here: http://wiki.restlet.org/docs_2.1/13-restlet/21-restlet/318-restlet/303-restlet.html#dsy303-restlet_gwt
