After over three years of iteratively adding features to Vaadin 6, the long waited Vaadin 7 is finally almost done. The three main goals areas of the new framework version are
- Give more power and freedom to developers.
- Make extending and plugging Vaadin simpler.
- Clean up where it smells.
In this presentation we cover most of the major changes in Vaadin 7 and dive deeper to the most important ones after giving a brief overview to Vaadin framework in general.

Background: Basics of Vaadin Framework
Dozens of toolkits offer a wide range of widgets to build rich web applications on top of HTML5 platform. For a real world application the included widgetset is rarely enough and development of custom user interface components is required. Design of a reusable component is far from trivial. In this presentation Joonas Lehtinen, one of the authors of the popular Vaadin Framework shows how a new component can be designed and implemented from scratch. Topics covered include considerations for choosing DOM structure, finding a balance between performance and features, implementation considerations and testing the component. During the presentation a new component is implemented from scratch with Google Web Toolkit and packaged as a Vaadin Framework add-on ready for use by third parties.
