Description S. Cook

Steps to recreate the exception:
1. Open Artifact Explorer
2. Right click on a folder in the Art.Expl. that is NOT empty.
3. Select 'Delete Artifact'.
4. Select 'Yes' when asked "Are you sure you want to delete this artifact and all of the default hierarchy children?".
5. You receive the OSEE Error with the exception (see below).

Work around:
User can avoid this exception by manually deleting each child artifact inside the folder.
