Hello,
I am using @Push and what I see is the detach() method is called twice.
It seems UI.setSession(…) calls setPushConnection(null), which eventually calls detach() second time.
detach(); <-- first time
// Close the push connection when UI is detached. Otherwise the
// push connection and possibly VaadinSession will live on.
setPushConnection(null); <-- second time
In com.vaadin.server.communication.PushHandler:
@Override
public void onResume(AtmosphereResourceEvent event) {
// Log event on trace level
super.onResume(event);
disconnect(event); <-- this is going to call VaadinService.requestEnd(..) again
}
Any comments? Is it a configuration/coding mistake on my part?
Thanks.
