Please don't quote an entire 100+ line post, especially if it's the last post in the thread.

Yes. The defaults are just that -- default values. They should only be used to initialize the db table; you should never be referring to values in the defaults table or applying them to things in your addon. If you're currently doing this with AceDB:

local defaults = {
     global = {
          point = "TOP",
          x = 0,
          y = -100,
     }
}

local db = LibStub("AceDB-3.0"):New("MyAddonDB", defaults, true)
local cfg = db.global

SomeFrame:SetPoint(cfg.point, cfg.x, cfg.y)

Then using the method in my last post you would do this instead:

local defaults = {
     point = "TOP",
     x = 0,
     y = -100,
}

MyAddonDB = copyDefaults(defaults, MyAddonDB)
local cfg = MyAddonDB

SomeFrame:SetPoint(cfg.point, cfg.x, cfg.y)

However, if you want to offer profile support, I'd suggest you just continue using AceDB.

Also, this thread is very old. I suggest you check this more current one instead:
