I find that, although I request the creation of a session, I'm getting null:
WrappedSession ses = request.getWrappedSession(true);// true --> create one if none existingassert ses !=null;// explodes!
This code is being called by my login button event handler. The request is the the one that was given to me when I created the GUI: init(VaadinRequest request); Should I be getting a new request in the button event handler?
Perhaps a bug or perhaps my misunderstanding (please extend the documentation if so).
Anyway, thought you'd like to know. I'm avoiding it by this instead:
