The $SESSION->questionnaire variable is used in many places without any check that it exists beforehand. This can throw errors when accessing a page through a bookmark for the first time in your browser session.
Log in on browser A, navigate to /mod/questionnaire/report.php
Copy url to browser B
- I got to the correct page but there was some warning code at the top:
Warning: Creating default object from empty value in /vle/www_root/mod/questionnaire/report.php on line 107
I think this affects new pages: fbsections, fbsettings, and settings as well as existing pages myreport, qsettings, questions, report and show_nonrespondents.
I'm a bit worried about preview.php which overwrites any existing $SESSION->questionniare with new StdClass(). I don't think it should do that?
