It's not.

Using the forward button of your browser changes the URL to 
#GoodbyePlace:World!, which the PlaceHistoryHandler detects. Itthen calls 
your PlaceHistoryMapper to transform that to a Place and call the goTo. 
Even if you cancel the goTo, the URL has already been changed, as it was 
the initial trigger.

browser forward button does not respect mayStop

[Constantino]

When I execute this app:

http://code.google.com/p/google-web-toolkit/downloads/detail?name=Tutorial-hellomvp-2.1.zip

I initially click on the "Say good-bye" link, then click on "OK" and I
see the "Good-bye" message.

Then I click on the back button to see the hello activity again.

This time instead of clicking on the link I click on the browser
forward button, it will:

- ask the message returned by the mayStop method
- before I click on ok or cancel the URL is already changed
- if I click cancel the URL will stay "http://127.0.0.1:/
hellomvp.html?gwt.codesvr=127.0.0.1:9997#GoodbyePlace:World!" but the
hello activity is still being displayed

Looks like a bug in GWT, isn't it?

Regards,
   Constantino
