RequestFactory Entity's parameter: List<OfOtherEntity> is null on client. On server is ok


RequestFactory Entity's parameter: List<OfOtherEntity> is null on client. On server is ok

may help you . By default gwt does not attach collection entities when fetching the object. You need to use the .with("ingredients") on your rf request. Make sure you have a getIngredients method in your pizza class. The rf request context will use this to fetch the ingredients. You may also need to make sure you have a transaction open if you are fetching this from something like hibernate. This will make sure the rf context can use an attached entity when retrieving the ingredients for your pizza.
Note that you don't want to use the with("getIngredients") the rf context will call the get method correctly.
code :
context.get().with("ingredients").fire(new Receiver<>)

GWT RequestFactory: using server classes in client package

GWT RequestFactory: using server classes in client package

I think the issue was by ths following , I ran into the same problem awhile back. There is nothing wrong with your code. By default, the GWT Compiler will not include classes referenced by annotations for compilation, which is crazy. So, the reason that you are seeing AnnotatedRfqService cannot be resolved to a type is because those classes aren't actually being compiled at all. The solution is to run the Java Compiler (through Ant, presumably) to compile everything before you try to compile the GWT module.
I asked (and answered) the same question here: https://stackoverflow.com/a/8766677/291180

should help you out So, I think, I found solution. I made changes to function, which create RequestContext:
code :
  private void edit(MyProxy proxy) {

    RequestContext reqCtx = clientFactory.getRequestFactory().Request();

    if (proxy == null) {
      // create proxy first time
      proxy = reqCtx.create(UserAndAccountProxy.class);
    } else {
      // create immutable copy
      proxy = reqCtx.edit(proxy);
    }

    final UserAndAccountProxy tmp = proxy;

    reqCtx.saveAndReturnMyProxy(proxy).to(new Receiver<MyProxy>() {

      @Override
      public void onFailure(ServerFailure error) {
        eventBus.showErrorInformation(error.getMessage());
        //recursive call with already filled proxy
        edit(tmp);
      }

      @Override
      public void onSuccess(UserAndAccountProxy response) {
        eventBus.showInformation("It`s ok!");
        eventBus.goToMainPage(null);
      }
    });
    // start editing with editor
    getView().onEdit(tmp, reqCtx);
  }

Hope this helps Construct a String by joining the elements of the List and provide that as a uri variable.
code :
String listOfIds = cartItemsId.stream().map(Object::toString).collect(Collectors.joining(","));
restTemplate.exchange("http://xxx.xx.xx.xx:8081/api/cart-items?cartItemsId={ids}",
    HttpMethod.POST, httpEntity, Void.class, listOfIds);

Does that help I guess that the NPE is because backlog is null in agency.getBacklog().getId()
If you take a look on the database and table backlog I think you see that agency_id is null. Therefore Backlogs cannot be attached to Agency.
code :
agency.setBacklog(new Backlog());
Backlog backlog = new Backlog();
agency.setBacklog(backlog);
backlog.setAgency(agency); // this should do the fix
@OneToOne(optional = true ...
private Backlog backlog;
@PrePersist
private void prePersist() {
   // add needed NPE checks etc...
   backlog.setAgency(this);
}

will help you Well, I realize that my post isn't precise answer to your question, but it's just my experience. In fact, there is just a question how to deliver data from server to client. I faced with some task couple years ago, and found for yourself an approach that make my life easier. To explain it, I want to specify my reasons:
You have to have full data delivery by requesting it from client - it's straight, natural way to requesting data; You don't want to create and support 2 different models of full data delivery: one by requesting from client and second by pushing from server; But you need to inform client about some changes on server side;
