RequestBuilder makes an AJAX call. It doesn't redirect the browser.
use setLocation for that, which I think is in the standard GWT API
someplace. Otherwise, use some JSNI to do:
window.location.href = http://whatever.com/;;
if you really meant to make an AJAX call: Yes, you need a callback.
You don't have to put anything in it, though.

Hi all,
I'm trying to do the following.
As part of how I'm modeling my exception handling, I decided that to
be consistent with my current Struts model - I would redirect the
user to a generic error page in case of an error. Thus, any exceptions
in the GWT should also be handled in the same manner.
I figured I could just use the RequestBuilder to send my request
along. However, I see that the problem here is that it requires a
RequestCallback instance in order to make the request. I probably
could fake a callback and let it pass, but I wanted to check with the
experts to see if there was a more appropriate way to do this. Does
this mean that there is no way of making a request/call to the server
without providing a callback?
Thanks
Suri
