Attachment Cateogry Exercise -- can still delete attachment
I am going through the Case Attaachments part of the course and running into difficulty with the Exercise. The scenario and approach seems rather straight forward but I cannot get my attachment to not be deletable. I never get the expected 'insufficient privlaeges error'. This holds true even after downloading the solution jar.
I very well may be missing something obvious but haven't been able to spot anything yet.
