Re: Does GWT 2.3 provide Synchronous RPC?

You dont want a sync interface for the simple reason that javascript
in the browser is single threaded. If requests back to the server were
sync and not async, your browser would freeze until the response from
the server completed. Even if the request was fast the user would
notice a freeze for even a fraction of second. Imagine a browser that
froze for a second or more each time a request went back to the server
- that would be a disaster.
