I am trying to create Vaadin 7 elements, and it would be useful if I could somehow use polymer elements like these directly → http://vaadin.imtqy.com/gwt-polymer-elements/demo/#paper/ButtonSample
However, there is no clear explanation or guide on how to directly add polymer elements to the Vaadin app.
If you want to use server side web components, there is an experimental addon from vaadin. Here you will find a demo application.
