Hi! In the University of Valencia are testing the Planner View.
We have read the documentation and the planner package is working well.
We would like to get the code with the Standard callbacks, we haven't found the patch to add the these callbacks in dotlrn.
"Standard callbacks: These callbacks are implemented once in the dotlrn package because there's no difference in the code needed for all packages."
1.planner::extend_form
2.planner::insert_object
Thanks for share your work
