Description

Failed to add a lesson to the front page. Offending line is in mod\lesson\mod_form.php 248:

if ($this->_cm->id != $mod->id)

I can't any references to the _cm variable so that may be a starting point.

We are having this same issue with the Lesson module. Ours is:

"Notice: Trying to get property of a non-object in mod/lesson/mod_form.php in line 248"

Not that this explains why we had the problem, but a re-install managed to clear things up for us. We were also having many database errors with the Exercise and Lesson modules, but those are also gone now.
