Dear Lindsay,
Thank you so much for your answer. Very helpful 🙂
Regarding the different version (10.1 and 10.2): We're working with ArcGIS Server 10.2, but personally and from this moment I like the procedure of using a relationship class for the feature set and the table, which stores the comments, more comfortable.
So... Is it also possible or is there any reason against using the 10.1 version (with relationship class) on ArcGIS Server 10.2?
Thanks a lot,
Dominik
