WoWInterface - Summoning raid frames has nil units

I'm using oUF to build raid frames and following some work that Rainrider has done: https://github.com/Rainrider/oUF_Lay....lua#L110-L132

However, when doing this, I sometimes get this error:

Code:

7x AelUI\unitframes\elements\init.lua:9: Wrong object type for function

The line which it complains about is

Code:

self:RegisterForClicks('AnyUp')

But there's also other weird things going on, like even if I comment out that line, it only shows a single unit (the other one seems to be there, but not styled).

I wonder if this is somehow related to https://www.wowinterface.com/forums/...ad.php?t=56943 ?

That said, I am using version 9.3.1 of oUF, so I'm not so sure this would be the case.

Any help would be appreciated! Also happy to post more details if needed. :)

Edit:

For the record, this is the code I'm using to spawn the groups:

Code:

local raidFrame = CreateFrame('Frame', nil, UIParent)

raidFrame:SetPoint('BOTTOMLEFT', UIParent, 'BOTTOMLEFT', 620, 10)

raidFrame:SetSize(1, 1)



-- local raid = {}

for i = 1, NUM_RAID_GROUPS do

        print('SPAWN GROUP', i)

        local group = self:SpawnHeader(

                'aelUI_raid', nil, 'raid',

                'showRaid', true,

                -- 'showPlayer', true,

                'maxColumn', 1,

                'unitsPerColumn', 5,

                'columnAnchorPoint', 'LEFT',

                'yOffset', -6,

                'groupFilter', i,

                'oUF-initialConfigFunction', [[

                        self:SetWidth(70)

                        self:SetHeight(58)

                ]]

        )



        group:SetParent(raidFrame)

        group:SetPoint('BOTTOMLEFT', (90 * (i - 1)), 0)

end
