Hi all
I try to integrate vaadin with guice but i have nullPointerException. Can you take a few minutes to check my code? 
[code]
public class CdiUiProvider extends DefaultUIProvider implements Serializable {
private static final long serialVersionUID = 8043964411848504777L;
@Inject
private MyUI vaadinUI;
@Override
public Class<? extends UI> getUIClass(UIClassSelectionEvent event) {
return CoproprieteUI.class;
}
@Override
public UI createInstance(UICreateEvent event) {
return vaadinUI;
}
}
[/code][code]
public class CdiVaadinServlet extends VaadinServlet {
@Inject
private Provider<CdiUiProvider> applicationProvider;
@SuppressWarnings("serial")
private final SessionInitListener sessionInitListener = new SessionInitListener() {
@Override
public void sessionInit(SessionInitEvent event) throws ServiceException {
final VaadinSession session = event.getSession();
session.addUIProvider(applicationProvider.get());
}
};
@Override
public void init(ServletConfig servletConfig) throws ServletException {
super.init(servletConfig);
getService().addSessionInitListener(sessionInitListener);
}
}
