When I remove my write access right for a given field and a workflow's transition has to write a value on this field (see functionnal test Tuleap-200), I've got the following error :
PHP Fatal error: Call to undefined method Transition_PostAction_CIBuild::bypassPermissions() in /usr/share/codendi/plugins/tracker/include/workflow/Transition.class.php on line 356, referer:

setUp -> On transition, create first a CI job, then conditions on date, and remove access rights for the date field (do in testlink Tuleap-243 and then Tuleap-200 tests). Your workflow must not be activated. The fatal error may appear.
