An asynchronous call calls onFailure instead of onSuccess, although the information comes from the database. What is the reason, comrades?
public class Auth extends Composite { interface AuthUiBinder extends UiBinder<HTMLPanel, Auth> { } @UiField TextBox login; @UiField PasswordTextBox password; @UiField Button signin; private static AuthUiBinder ourUiBinder = GWT.create(AuthUiBinder.class); public Auth() { initWidget(ourUiBinder.createAndBindUi(this)); signin.addClickHandler(new ClickHandler() { public void onClick(ClickEvent clickEvent) { UserService.App.getInstance().getAllUsers(new AsyncCallback<List<User>>() { public void onFailure(Throwable caught) { Window.alert(login.getText() + " " + password.getText()); } public void onSuccess(List<User> result) { for (User user: result) { if (login.getText().equals(user.getLogin()) && password.getText().equals(user.getPassword())){ History.newItem("greetingUI"); RootPanel.get("body").clear(); RootPanel.get("body").add(new Greeting(user.getName())); } } } }); } }); }} Log from the console
