The Plagiarism API has the function "print_disclosure" to print a notice to the students that the assignment will be scanned for plagiarism.
This function is called correctly in the former assignment module. However, the assignment module view page does not call this function any more.
I temporarily add the following call to the function view_submission_page() in /mod/assign/locallib.php:
and saw that it worked.
I think this is a missing in the new assignment component.
