Unfortunately, no, at least not out of the box. Vaadin uses a server-side architecture, which means that all widget states are stored on the server, not in the browserโs memory, which makes the widgets server-dependent. The connection between the client part of the widget and the server is implemented deep in the Vaadin core, so I think that for the widget to work, it will take quite a lot of work to work in a clean GWT environment.
