      Description

      On making a deep analysis on a significant (for us ) number of records about an unexpected SCO status found in the mdl_scorm_scoes_track of a medium-sized Moodle installation with plenty of AICC HACP based packages, we found a flaw in the business logic related with the evaluation of the status by the Mastery Score mechanism.

      Shortly, the failure is due to a bad, in this case, usage of PHP empty() which excludes 0 from being a valid value.
