When making the LAM calls, I added all controls to a local table.
Afterwards doing something like

for _, v in ipairs(controls) do
    local onShowFunc = v:GetHandler('OnShow')
    if (onShowFunc ~= nil) then onShowFunc() end
end

or

for _, v in ipairs(controls) do
    v:SetHidden(true)
    v:SetHidden(false)
end

works, but not for sliders. I have looked at it for half an hour now, but it beats me
Switching to another panel and back, still works though...
Aah, the wonders of eso & lua
