Why use Formio?

Why should you prefer Formio library over other frameworks that allow forms processing? It is really simple to use, non-invasive and easy-integrable tool that can be used almost everywhere (in servlets, portlets, but also in component frameworks). It is useful lightweight library rather than a complex framework with its own lifecycle and more or less complicated widgets/components.
