I've been testing my app with GWT 2.6rc4 today. I ran into an issue where I
wasn't being prompted before navigating away from a presenter who returned
non-null in mayStop(). This should be opening a native confirm dialog and
asking the user OK/CANCEL. It works fine in GWT 2.5.1, but in 2.6rc4 it
always returns false without ever prompting the user. I switched back to
2.5.1 without changing any code and it works as expected.
I couldn't find anywhere on this group or the main GWT Google Group where
changes to Window.confirm() were being discussed.
The following code hasn't changed in a while. Looking through the recent
history of the Window class, nothing really stands out that I could see.
public static native boolean confirm(String msg) /*-{
return $wnd.confirm(msg);
}-*/;
My code isn't really doing anything complicated, it is basically the
following:
boolean discardChanges = Window.confirm(myPresenter.mayStop());
