             Summary: Session.exists() returns false when ThreadContext#session is not set to current session
                 Key: WICKET-5040
                 URL: https://issues.apache.org/jira/browse/WICKET-5040
             Project: Wicket
          Issue Type: Bug
          Components: wicket
    Affects Versions: 6.5.0
            Reporter: Sven Meier
            Assignee: Sven Meier


There are several places in Wicket which check for the existence of a Session before actually getting a reference to it, e.g. FeedbackCollector:

	public final List<FeedbackMessage> collect(final IFeedbackMessageFilter filter)
	{
		...
		if (includeSession && Session.exists())
		{
			messages.addAll(Session.get().getFeedbackMessages().messages(filter));
		}
	}

If no one has called Session#get(), all calls to Session#exists() return false although a session might exist in the session store, i.e. it might just not be set to ThreadContext#session already.
