Name update error

[Toran]

Hi,

I get an error that seems to only spawn when I'm forced off my mount in the argent tournament area. Error is:

layout.lua:192: bad argument #1 to 'lower' (string expected, got nil)
layout.lua:192: in function `UNIT_NAME_UPDATE'
layout.lua:276: in function <oUF_Lyn\layout.lua:214>

Code involved in the "name update" area is:

local updateName = function(self, event, unit)
	if(self.unit ~= unit) then return end

	local name = UnitName(unit)
    self.Name:SetText(string.lower(name))
	
	if unit=="targettarget" then
		local totName = UnitName(unit)
		local pName = UnitName("player")
		if totName==pName then
			self.Name:SetTextColor(0.9, 0.5, 0.2)
		else
			self.Name:SetTextColor(1,1,1)
		end
	else
		self.Name:SetTextColor(1,1,1)
	end
	   
    if unit=="target" then -- Show level value on targets only
		updateLevel(self, unit, name)      
    end
end

I boldfaced the part in the code that the error seems to align with. Anyone have an idea what is causing it and how to fix? Thank you!

Not sure what would cause that; but you can fix it like this:

local name = UnitName(unit)
if not name then return end
self.Name:SetText(string.lower(name))

It looks like there needs to be another check in there to validate that unit exists. If it only happens when you are forced off of your mount then it sounds like it was in the process of updating the mount's information and then lost the information mid calculation.

If you add the following line just above that offending line it should resolve the problem.

if ( not name ) then return end

Thus, if you weren't aware, not going any further if all of a sudden there is no unit to get details for.

Edit: D'oh beaten..

Worked great. Thanks for the fast replies.
