Relationship between FilterAura and button?

Before oUF 11, I use customFilter to consolidate all bolster in mythic plus.

The code is what I did before, but in oUF 11, button no longer accessable in FilterAura.

Lua Code:

local function PreUpdate(element)
    element.bolster = 0
    element.bolsterIndex = nil
end
 
local function CustomFilter(element, unit, button, name, _, _, _, _, _, _, _, _, spellID)
    if name and spellID == 209859 then
        element.bolster = element.bolster + 1
        if not element.bolsterIndex then
            element.bolsterIndex = button
            return true
        end
    end
end
 
local function PostUpdate(element)
    local button = element.bolsterIndex
    if button then
        button.Count:SetText(element.bolster)
    end
end

What I currently do is add a new attribute in 'updateAura'.

Code:

button.spellID = aura.spellId

Lua Code:

local BOLSTER_ID = 209859
 
local function PreUpdate(element)
    element.numBolster = 0
end
 
local function FilterAura(element, _, data)
    if data.name and data.spellId == BOLSTER_ID then
        element.numBolster = element.numBolster + 1
        return element.numBolster == 1
    end
end
 
local function PostUpdate(element)
    if element.numBolster == 0 then return end
 
    for i = 1, #element.sortedBuffs do
        local button = element[i]
        if button.spellID == BOLSTER_ID then
            button.Count:SetText(element.numBolster)
            break
        end
    end
end

Well, it had to happen because the update process happens in stages now, filtering > sorting > redrawing. Buttons get updated only at the redrawing stage, but before that we work with raw aura data. If I were you, I'd use PostUpdateButton instead of PostUpdate since it gives you both the button and the aura data, but you won't need the latter in this case. I drycoded it, but this should do the trick.

Lua Code:

local BOLSTER_ID = 209859
 
local function PreUpdate(element)
    element.bolsterStacks = 0
    element.bolsterInstanceID = nil
end
 
local function FilterAura(element, _, data)
    if data.name and data.spellId == BOLSTER_ID then
        if not element.bolsterInstanceID then
            element.bolsterInstanceID = data.auraInstanceID
        end
 
        element.bolsterStacks = element.bolsterStacks + 1
        return element.bolsterStacks == 1
    end
end
 
local function PostUpdateButton(element, button)
    if not element.bolsterInstanceID then return end
    if element.bolsterInstanceID ~= button.auraInstanceID then return end
 
    button.Count:SetText(element.bolsterStacks)
end

Btw, your code will only work properly during full updates. But worry not, there's this new PR in the works atm, it'll allow you to mess with stuff via PostUpdateInfo before it's sent over to sorting.

Could you provide an example for me, with PostUpdateInfo?
