How do I make right-click menu for ToT frame?

[Eveigh]

Hello!
I'm little confused. I use the following code to implement right-click menus on frames:

local function menu(self)
	local dropdown = _G[string.format('%sFrameDropDown', string.gsub(self.unit, '(.)', string.upper, 1))]

	if dropdown then
		ToggleDropDownMenu(1, nil, dropdown, 'cursor')
	elseif (self.unit:match('party')) then
		ToggleDropDownMenu(1, nil, _G[format('PartyMemberFrame%dDropDown', self.id)], 'cursor')
	else
		FriendsDropDown.unit = self.unit
		FriendsDropDown.id = self.id
		FriendsDropDown.initialize = RaidFrameDropDown_Initialize
		ToggleDropDownMenu(1, nil, FriendsDropDown, 'cursor')
	end
end

Thanks to yj589794.
It is working for all frames, except ToT frame. On ToT frame it gives me error:

Can somebody give me some insight? I can't understand why it calls GetRaidRosterInfo, nor how to make it not to do that.
BTW, it's for live, not for beta/ptr.
Thanks!
