PLAYER_LOGIN event does not fire on first character login in module

[zork]

I got an wierd issue.

On first login of a character the Visibility function does not get called. But on every /reload it will.

I have a module. The Enable looks like

local Enable = function(self, unit)
  local element = self.DemonicFury
  if(element and unit == 'player') then
    element.__owner = self
    element.ForceUpdate = ForceUpdate
 
    self:RegisterEvent('UNIT_POWER', Path, true)
    self:RegisterEvent('UNIT_DISPLAYPOWER', Path, true)
    self:RegisterEvent('PLAYER_TALENT_UPDATE', Visibility, true)
    self:RegisterEvent("SPELLS_CHANGED", Visibility, true)
    self:RegisterEvent("UPDATE_OVERRIDE_ACTIONBAR", Visibility, true)
 
    local helper = CreateFrame("Frame") --this is needed...adding player_login to the visivility events doesn't do anything
    helper:RegisterEvent("PLAYER_LOGIN")
    helper:SetScript("OnEvent", function() Visibility(self) end)
 
    return true
  end
end

If I add

    self:RegisterEvent("PLAYER_LOGIN", Visibility, true)

and remove the helper on the first login of a character on the MoP beta servers the Visibility function is not being called at all.

But on every /reload it does work as expected.

Thus I added the helper and with that it works like intended.

What could cause this?

I'm betting your Enable is called after the point where PLAYER_LOGIN fires. Try registering it in the main chunk.

PLAYER_LOGIN has already fired by the time elements are getting Enabled on a fresh login. Anything you need to do when an element is enabled, you should just do it directly inside the Enable function.

You can also check IsLoggedIn() if you need to make sure.
