Comfort message on redirect

General
1

When redirecting (e.g. to PayPal) I use something like:

ui.getSession().close(); UI.getCurrent().getPage().setLocation(newLocation); but when the destination server takes time to respond I don’t get any indication that anything’s happening, and any Notifications I raise are lost.

Is there a clean way to show a comfort message like “Redirecting…” before making the redirect?

Thanks

You could try using some Javascript with getPage().getJavaScript().execute(script); and try to blank the page and add some text or create some popup with pure javascript. That might work.

Ok I lost my way a bit there, partly due to making some allowances for Push mode.
It seems if I do

Notification.show(header, msg, Type.HUMANIZED_MESSAGE);
UI ui = UI.getCurrent();
ui.getPushConfiguration().setPushMode(PushMode.DISABLED);      
ui.getCurrent().getPage().setLocation(newLocation);
ui.getSession().close();

It ends well.
