- A mortgage application that requires the user to complete a 12-page application, but mandates “Don’t Hit the Back Button” because the site’s AJAX implementation breaks that function?if a user realizes he or she made a mistake on a previous page, the user is stuck.
- An e-commerce site warning that a user’s credit card will be charged twice if he or she presses the Submit button twice, yet the site just hangs while processing the initial submit click and offers no confirmation in the meantime
- Of course, the 404 (page not found) and 500 (internal server) errors with which every web user is familiar

When GWT 1.5 arrives, Johnson said it will also offer full language support for Java 1.5 (Generics, etc.). This feature would enhance the current 1.4 version’s features, notably AJAX internationalization, which uses message templates to enable developers to compile code for 400 locales from one code base, and browser history support.
