1) Web application is using the root context ("/")
1) form.add(new Button("mybutton"));
2) Button is clicked on any WebPage that is NOT MOUNTED
WebRequestCodingStrategy.encode appends './' to the URL. The page is redirected to "http://www.mysite.com/./" It works fine in Firefox and Opera, but in IE an HTTP 404 ('.' page is not found) is rendered.
Mounting the home page to something like '/home' solved the problem ('./' is not appended, but this causes a redirect every time a use hits the page).
