When creating a new feedback, a quick warning appears stating access to a non defined class variable id on line 296

here are the involved line (in the file mod/feedback/lib.php)

function feedback_set_events($feedback) {
// adding the feedback to the eventtable (I have seen this at quiz-module)
===> delete_records('event', 'modulename', 'feedback', 'instance', $feedback->id);
...

should be changed in

if (isset($feedback->id))

• it is reported in moodle core allthough the module is in the contributed area for the Moodle version I am using (1.9.2)
