Implementing autosave with Vaadin

There is some general knowlegde in the web about implementing autosave features in your web application. I’m wondering if there are some best practices or ready-made solutions for implementing autosave with Vaadin (forms with multiple different data input widgets). Searching through forums & add-ons did not help.

Bumping with some general information. Is it so, that autosave feature is not everyday requirement in Vaadin applications? General solutions are simple (for simple forms) but still would like to have a “best practice” with Vaadin.
