If you follow a link like this: https://[server_host]/secure/admin/EditNotifications!default.jspa?schemeId=12805, and the notification scheme ID does not exist, you get a page like this:
Note the "{0}" notification scheme banner at the top. What is this page, and what happens if I make edits on it? Where do they go?
This behavior is indeed interesting.
I've performed some tests in my instance, and you can't edit this notification scheme. You should see an error like the following.
Hope it helps :)
