GetRaidRosterInfo bug

Will return nil if a new person joins the raid. But only one time.
I tested this on the leveling realm, had someone join from the pve 100 realm.
once the game sees the player, even if that player logs out back in, the function won't return nil
anymore. ignore the print functions, that's just debug testing code.
I use this function when GROUP_ROSTER_UPDATE fires.

Code:

function GWL:GROUP_ROSTER_UPDATE()

  local Found = false

  local MaxMembers = GetNumGroupMembers()



  -- Preset the waitlist to Outside

  if WaitList then

    for Index, _ in pairs(WaitList) do

      WaitList[Index] = Outside

    end

  end



  -- Return if not in a group/raid.

  if MaxMembers > 0 then



    -- If first time joining a raid then start a new waitlist.

    if not RaidActive then

      ClearWaitList()

      RaidActive = true

    end



    for Index = 1, MaxMembers do



      -- Set player as in raid.

      local Player = GetRaidRosterInfo(Index)

      print('>', Player, Player == nil)

      if Player and Player ~= '' then

        Player = Ambiguate(GetRaidRosterInfo(Index), 'none')

        if Player then

          print(':', Player)

          WaitList[Player] = InRaid

        end

      end

    end

  else

    RaidActive = false

  end



  -- Save RaidActive status

  GalvinWaitListDB.RaidActive = RaidActive



  return Found

end

Not related to the bug, but:

Code:

      local Player = GetRaidRosterInfo(Index)

      print('>', Player, Player == nil)

      if Player and Player ~= '' then

        Player = Ambiguate(GetRaidRosterInfo(Index), 'none')

Why call GetRaidRosterInfo(Index) a second time on the last line, when you already called it and stored its value in the Player variable on the first line? Just do Player = Ambiguate(Player, 'none') there.

Oops, bug still remains though.

It sounds like the game isn't caching the player's info until you actually request it.

You may want to delay your GetRaidRosterInfo call to see if it always fails the first time you call it or only when you call it immediately after they join.
