oUF_Mu problem with class power and vehicle UI

[Maerlyns]

Hey

Since the author of oUF_Mu seems not to be active anymore I hope you could help me.

Every time I leave a vehicle (for example the mounts of the Argent Tournament) my class power like Holy Power doesn't work correctly. If you download the normal files you'll see that the frame doesn't show up again. That's easily fixed with taking every power in the function "VehicleVisibilityUpdate" but now the frame shows up and if I gain one Holy Power the frame doesn't show me that. With DK runes it works great. I couldn't find any mistake but well, I'm not very good at LUA.

All I have found in the code was this:

--=================================--
-- class points bars
--=================================--

local function cpPositionCalc(width, count)				-- calculate the position of the first point
	return 1-floor((width+2)*count/2)
end

local function PostUpdateRune(runes, rune, rid, start, duration, ready)
	local runetype = GetRuneType(rid)
	local r, g, b = unpack(oUF.colors.runes[runetype])
	if ready then
		rune:SetStatusBarColor(r, g, b)
	else
		rune:SetStatusBarColor(r*.6, g*.6, b*.6)
	end
end

local function VehicleVisibilityUpdate(self, event, unit)
	local element = self.Runes and self.Runes or self.TotemBar or self.ClassIcons or self.CPoints
	for i = 1, #element do
		if UnitHasVehicleUI('player') then
			element[i]:Hide()
		else
			element[i]:Show()
		end
	end
end

local function ShadowOrbsVisibilityUpdate(self, event, ...)
	local orbs = self.ClassIcons
	for i = 1, 3 do
		if UnitHasVehicleUI('player') or GetSpecialization() ~= 3 then
			orbs[i]:Hide()
		else
			orbs[i]:Show()
		end
	end
end

local function classPointHelper(self, class, pinfo)
	local w, h, count = pinfo.size.w, pinfo.size.h, pinfo.count
	if count < 5 and class ~= 'SHAMAN' then count = 5 end
	local points = {}
	for i = 1, count do
		local point = CreateFrame('StatusBar', nil, self)
		point:SetSize(w-2, h-2)
		point:SetStatusBarTexture(cfg.powertex)
		point.bg = point:CreateTexture(nil, 'BACKGROUND')
		point.bg:SetAllPoints(point)
		point.border = mu.createBorder(point)
		if class == 'DEATHKNIGHT' then
			local runetype = GetRuneType(i)
			local r, g, b = unpack(oUF.colors.runes[runetype])
			point.bg:SetTexture(r, g, b, 0.75)
			point.bg.multiplier = .25
		elseif class == 'ROGUE' or class == 'DRUID' then
			point:SetStatusBarColor(unpack(cpcolor[i]))
		end
		points[i] = point
		if i == 1 then
			point:SetPoint('BOTTOMLEFT', UIParent, 'CENTER', cpPositionCalc(w, pinfo.count), -109)
		else
			point:SetPoint('LEFT', points[i-1], 'RIGHT', 4, 0)
		end
	end
	return points
end

Could you please help me find the incorrect parts in this code?
