Vaadin - Form Data Saving into a second form

Add the following unit into your vaadin application (it runs under the lehel.sipos.vaadin package):

Vaadin

Vaadin is a web application framework for Rich Internet Applications (RIA). In contrast to Javascript libraries and browser-plugin based solutions, it features a robust server-side architecture. This means that the largest part of the application logic runs securely on the server. Google Web Toolkit (GWT) is used on the browser side to ensure a rich and fluent user experience.

JavaFX

JavaFX is the next step in the evolution of Java as a rich client platform. It is designed to provide a lightweight, hardware-accelerated Java UI platform for enterprise business applications. With JavaFX, developers can preserve existing investments by reusing Java libraries in their applications. They can even access native system capabilities, or seamlessly connect to server-based middleware applications.
