You can pass a url fragment argument like
Window.Location.replace(GWT.getHostPageBaseURL() + "#error=Something bad happened");
and then in your login page you have to check for url fragments (after #).
Similarly if you don't want to pollute your urls you can
set a cookie
use sessionStorage
use localStorage
to communicate the error state to the new page.
Hope that helps

Hello,--I have this small example. I am on the user page. In the constructor the UserInfo object is set. If something happens I want to redirect back to the login page, which I do like in the example below. Is there a possibility to display a message back on the login page like "An error eccurred bla bla bla. Please log in again." ?Thanks in advance.
public UserPanel() {setUserInfo();if (userInfo == null) {Window.Location.replace(GWT.getHostPageBaseURL()); }container = new MaterialContainer();container.setFontSize("1em");Widget mainMenu = createMenu();initWidget(mainMenu);}
