Weak Auras - need to see name of player giving the buff

[Tarien]

I'm trying to set up a weak aura to see various raid wide defensive cooldowns such as Devotion Aura, I can easily see this and the time remaining on the aura, but I also want to see who put the aura up. Can't figure out how to do this.

Anyone know or have any ideas?

Use a custom text (%c) with the following function:

function()
    return UnitName((select(8,UnitBuff(WeakAuras.CurrentUnit,"Devotion Aura"))) or "")
end

All this gives me is a question mark '?', it isn't returning the name of the person who cast the Devotion Aura.

EDIT: Using Power Word: Shield to test it, I changed it in the function you listed.
