Hello,
I wrote very simple vaadin application, which consists of simple Login
and Logout buttons.
Login code:
UsernamePasswordToken token = new
UsernamePasswordToken("test", "test");
token.setRememberMe(true);
currentUser.login(token);
Logout code:
currentUser.logout();
getMainWindow().getApplication().close();
the following error occurs after some login/logouts:
Caused by: java.lang.NullPointerException

Any idea ?
