Re: Getting username from url only works after refresh

Where and when and how is UserActivity constructed? Where does the UserPlace come from?

I've tried that before, and I didn't managed to get the username to be visible in my ViewImpl...

For example. This is the structure I have:

UserActivity

public class UserActivity extends AbstractActivity implements UserView.Presenter {


 private ClientFactory clientFactory;
 private String name;


 public UserActivity(UserPlace place, ClientFactory clientFactory) {
 this.name = place.getPlaceName();
 this.clientFactory = clientFactory;
 }


 @Override
 public void start(final AcceptsOneWidget containerWidget, EventBus eventBus) {
 UserView userView = clientFactory.getUserView();
 userView.setName(name);
 userView.setPresenter(this);
 containerWidget.setWidget(userView.asWidget());


 }


 @Override
 public void goTo(Place place) {
 clientFactory.getPlaceController().goTo(place);
 }


}

UserPlace

public class UserPlace extends Place {

private String username;

public UserPlace(String username) {

this.username = username;

}

public String getPlaceName() {

return username;

}

public static class Tokenizer implements PlaceTokenizer<UserPlace> {

@Override

public UserPlace getPlace(String token) {

return new UserPlace(token);

}

@Override

public String getToken(UserPlace place) {

return place.getPlaceName();

}

}

}

UserView

public interface UserView extends IsWidget {

void setName(String name);

void setPresenter(Presenter presenter);

public interface Presenter {

void goTo(Place place);

}

}

UserViewImpl

public class UserViewImpl extends Composite implements UserView {

        ...

public UserViewImpl() {

Widget mainMenu = createMenu();

initWidget(mainMenu);

}

        ...
}

How can I access the username I send from my LoginViewImpl like shown above in my UserViewImpl ? 

Thanks in advance

My login based application, requires to always know the username of the logged in user. (MVP) . So I'm getting the username from the url, but when the page opens after the login succeeded, I can't get the username from the url, because it does not appear to exists, but it is there. It only works after a refresh. Then I'm able to get the username. The URL is in the form http://127.0.0.1:8888/AdministrareBloc.html#AdminPlace:admin, where I'm splitting the String to only get the admin part. I thought this is because it downloads the code before verifying the user. So I placed a split point in my code like this: (I don't know if I placed it correctly) loginButton.addClickHandler(new ClickHandler() { @Override public void onClick(ClickEvent event) { final String username = usernameBox.getText(); final String password = passwordBox.getText(); GWT.runAsync(new RunAsyncCallback() { @Override public void onSuccess() { performUserConnection(username, password); } @Override public void onFailure(Throwable reason) { // TODO Auto-generated method stub } }); } }); private static void performUserConnection(String username, String password) { DBConnectionAsync rpcService = (DBConnectionAsync) GWT.create(DBConnection.class); ServiceDefTarget target = (ServiceDefTarget) rpcService; String moduleRelativeURL = GWT.getModuleBaseURL() + "DBConnectionImpl"; target.setServiceEntryPoint(moduleRelativeURL); rpcService.authenticateUser(username, password, new AsyncCallback<User>() { @Override public void onSuccess(User user) { if (user.getType().equals("User")) { String username = user.getUsername(); presenter.goTo(new UserPlace(username)); } else if (user.getType().equals("Admin")) { String username = user.getUsername(); presenter.goTo(new AdminPlace(username)); } } } } This is happening when the user clicks the login button. Is the split point placed correclty, or not ? How can I get the username without needing to refresh the page after a successful login ? Thanks in advance
