The Input validation for the Listname field now checks to see if the current value (group name) exists in the ($users) view. This causes a problem if you have a mail-in document with the same name as an access-list only group (which, I would think, is a common thing to do when giving a list of people access to a mail in db)
Just thought some people might find it as frustrating as I do when they suddenly see “A User name already exists by this name. Group names are not allowed to match exactly a User name. Please choose a different Group name.” while trying to save an existing group.
Funny, there is no such check in the “Database” form.
