No. If it can be "named", it should have a URL, and there's no reason that it wouldn't be in the browser history. Otherwise, don't use a place, but instead "bake" the feature within the activity (possibly move it to a PopupPanel/DialogPanel) > A I understand it, each Place is a new History token and you can't modify > the stack either because the browser manages it. > Yes.

It's kind of a hack though. That said, we definitely need a way, both for History and places, to replace the current item with a new one, and that could possibly be used in your case too. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
