There's no way to prevent navigation to a "hash" in a browser (there's no equivalent to onbeforeunload for onhashchange; there isn't for pushState/onpopstate either) so if you navigated using History.newItem() or your browser's history, there's no way you can prevent the URL to change.
You should code your app using PlaceController.goTo() for navigation (which means replacing all your Hyperlinks, if any, with Anchors+ClickHandlers), which will then call History.newItem() (and thus update the URL) only if the navigation is not cancelled by the user. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
