GWT new EntityProxy in #OneToOne with another EntityProxy from server - gwt

Question

I am just creating a new Proxy:
LayoutExampleRequest r = requestFactory.employeeRequest();
DepartmentProxy d = r.create(DepartmentProxy.class);
r.save(d);
departmentEditor.editProxy(d, r);
Then pass the Proxy and the Request(LayoutExampleRequest ) to my editor
driver.edit(proxy, request);
Until here ! everything works as espected. I can save Department objects with null EmployeeProxy. Now iam getting with a suggest box Proxys of EmployeeProxy from the server.
search = new SuggestBox(new SuggestOracle() {
#Override
public void requestSuggestions(final Request request,final Callback callback) {
System.out.println(request.getQuery());
//ignore less than 3
if(request.getQuery().length() > 3){
requestFactory.employeeRequest().search(request.getQuery()).fire(new Receiver<List<EmployeeProxy>>(){
#Override
public void onSuccess(List<EmployeeProxy> response) {
List<MySuggestion<EmployeeProxy>> suggestions = new ArrayList<MySuggestion<EmployeeProxy>>();
for(EmployeeProxy e:response){
MySuggestion<EmployeeProxy> suggestion = new MySuggestion<EmployeeProxy>();
suggestion.setModel(e,e.getFirstName(),e.getFirstName()+" "+e.getLastName());
suggestions.add(suggestion);
}
callback.onSuggestionsReady(request, new Response(suggestions));
}
});
}
}
});
MySuggestion is a wrapper class to handle the EmployeeProxy.
Now i want to add this EmployeeProxy to my DeparmentProxy since i have a #OneToOne on JPA.
search.addSelectionHandler(new SelectionHandler<SuggestOracle.Suggestion>() {
#Override
public void onSelection(SelectionEvent<Suggestion> event) {
MySuggestion<EmployeeProxy> s = (MySuggestion<EmployeeProxy>)event.getSelectedItem();
proxy.setSupervisor(s.getModel());
}
});
proxy is the EntityProxy for Department (I sent to my editor) driver.edit(proxy, request);
then i fire the driver:
departmentEditor.getDriver().flush().fire(new Receiver<Void>() {
#Override
public void onSuccess(Void response) {
Window.alert("Success");
// refresh the datagrid
Range range = dataGrid.getVisibleRange();
dataGrid.setVisibleRangeAndClearData(range, true); //1st way
// create a new DepartmentProxy to bind to the Editor.
createProxy();
// change button text
updateButton.setText("Save");
}
#Override
public void onConstraintViolation(Set<ConstraintViolation<?>> violations) {
for(ConstraintViolation v :violations){
Window.alert(v.getMessage()+" "+v.getPropertyPath());
}
}
#Override
public void onFailure(ServerFailure error) {
Window.alert(error.getMessage());
}
});
The problem is iam getting ConstraintViolations from the EmployeeProxy, is like the driver atach the EmployeeProxy but with null values.
(Iam validating my Entityes with JSR-330 )
Dont know how to make a relationship with a new Proxy with other taked from the server. in a #OneToOne relationship
Any help would be nice!
Thank you
/* UPDATE */
Something like this but with editor
final LayoutExampleRequest r = requestFactory.employeeRequest();
final DepartmentProxy d = r.create(DepartmentProxy.class);
d.setName("Name");
d.setService(Service.CONTRACT_MANAGMENT);
// get some random employee
requestFactory.employeeRequest().findById(1).fire(new Receiver<EmployeeProxy>() {
#Override
public void onSuccess(EmployeeProxy response) {
d.setSupervisor(response);
r.save(d).fire(new Receiver<DepartmentProxy>() {
#Override
public void onSuccess(DepartmentProxy response) {
Window.alert("Kidding me! why editor cant get it work =p?");
}
});
}
});

Answer 1

The problem was i put on my editor properties of the EmployeeProxy so when a user select the employeproxy would see information about it, so i delete them and then do the same and now works.
Is like GWT when detects properties from another proxy on the editor thinks you will fill it. And the line:
proxy.setSupervisor(s.getModel());
doesn't works.
