Hello Martin, I have updated our application to wicket-8 and NPE is not reproducible anymore Now I have even more weird situation: on every second page reload I'm not getting WebSocketBehavior::onConnect messages (Chrome error console empty) I suspect this might be caused by my code :(
The logic I need to implement is: In case particular page is loaded, and special one-time hash is passed as page parameter, I need to drop existing session And set session Auth data using hash received. So I'm checking if AbstractAuthenticatedWebSession::isSignedIn() == true I call invalidateNow() and replaceSession() Maybe this need to be implemented somehow differently? Maybe I can put breakpoint somewhere to be able to debug this?
