Hi guys. Before posting a bug, I would like to post it here as I might get my facts wrong.
I created a sample application with vaadin 7.0.beta9 and authorize into vk.com. I create a button and handle response parameters after oauth mechanism has done its job. I am running vaadin with inside embedded jetty server. If authorization succeeds, then everything fine and main page of my application renders flawlessly. But if I deny authorization, then exception is thrown. The request uri for vaadin servlet is “http://localhost:8080/#error=access_denied&error_reason=user_denied&error_description=User denied your request”. It seems that the whitespace in “error_reason” parameter is the cause here.
