Is there a possiblity to display a message on the page you are redirected to?

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);

}
