event for call to arms

[SignOfDoom]

hi
im searching for a event that fires after the call to arms has changed. I already tried: "LFG_UPDATE, LFG_ROLE_UPDATE, LFG_QUEUE_STATUS_UPDATE, LFG_UPDATE_RANDOM_INFO" but none of them is working.
Is there any other event i can use to get what i want or do i have to put my function in the onUpdate handler

I think this should work (updated when the random LFD is updated):

local f = CreateFrame("Frame")
f:RegisterEvent("LFG_UPDATE_RANDOM_INFO")
f:SetScript("OnEvent", function(f, event)
  local dungeonID = LFDQueueFrame.type
  if type(dungeonID) == "number" then
    for i = 1, LFG_ROLE_NUM_SHORTAGE_TYPES do
      local eligible, forTank, forHealer, forDamage, itemCount, money, xp = GetLFGRoleShortageRewards(dungeonID, i)
      if eligible and (itemCount ~= 0 or money ~= 0 or xp ~= 0) then -- show only if eligible and has a reward
        if forTank then print("Call to Arms: Tank") end
        if forHealer then print("Call to Arms: Healer") end
        if forDamage then print("Call to Arms: DPS") end
      end
    end
  end
end)

Like you suggest a OnUpdate with a sleep timer would be better, because I didn't find a event for this. Blizzard simply updates the CtA information when the frame is shown and player toggles between the various dungeon types. The API is what gets the new data from the server, not that bad tough. Keeping it on a 5 sec loop should be plenty.
