Hello, using rap 3.3 or 3.2, the ExitConfirmation service message doesn't work with Firefox 56 or Chrome 61.
Closing session, the exit message compares only few times

It works with Internet explorer.

Simple snippet:

public class Test1 implements EntryPoint {

    @Override
    public int createUI() {
        RWT.getClient().getService(ExitConfirmation.class).setMessage("hello");

        Shell s = new Shell();
        s.setText("Hello");
        s.setBounds(0, 0, 300, 300);
        s.open();
        return 0;
    }

}

Hi,
it seems there are some ongoing changes in Firefox and Chrome related to "beforeunload" event. Just tested on recent (Chrome 61 and Firefox 56) browsers and "beforeunload" event is not fired at all. Custom message is no longer supported in most browsers and we will remove the ExitConfirmation client service soon.
Regards,
Ivan

... in order to show the dialog a user gesture is required before (at least in Chrome 60+). See [1]. In my tests the same is valid for Firefox.

It still works for me on Chrome 61, providing the page has been interacted with. It's still a useful feature. I use it to warn a user has unsaved changed before navigating away. They only have unsaved changed if they have interacted with the page.

The custom message doesn't display in Chrome any more but please don't remove the service.
IE11 still display the supplied message.

Hi Chris,
once IE stop displaying a custom message ExitConfirmation#set/getMessage will not make sense anymore. We will keep the service, but will probably change the API to something like ExitConfirmation#set/getEnabled() or ExitConfirmation#enable().

Ivan
