Changeset 9420 for main/waeup.kofa/trunk

Timestamp:

25 Oct 2012, 21:52:10 (12 years ago)

Author:

Henrik Bettermann

Message:

Reorganize ICourseTicket. Add ICourseTicketImport which validates a new field called level_session.

Customize checkConversion of CourseTicketProcessor?:
If level_session is provided in row the importer checks if
the parent studylevel exists and if its level_session
attribute corresponds with the expected value in row. The error message
then tells us why course result import fails.
