Alex Deparvu updated SLING-7074:
--------------------------------
Attachment: SLING-7074.patch
attaching proposed patch.
tried to fallback to defaults whenever possible. could not find a way to expose
the archives, so this specific info is borderline useless (at least it shows
the count). did not cover the path param at all in tests, but I'm willing to
update the patch if this is needed.
Bonus, I added a debug log for value updates. This was there for a single value
type but went away, I found it useful so I added it for all cases. If it's not
interesting, I can remove it and update a new version of the patch.
[~mreutegg] how does this look to you?
