Hello,
the source code of http://demo.vaadin.com/sampler/ is available? if yes, where?
thank you
Sorry, it is not publicly available. If I remember correctly, this is because it uses some third party libraries whose licensing terms prevent us from sharing the related sources.
You can get snippets of code for individual components from inside the sampler (one of the icons top right), but the whole application is not available in source form.
