Hello guys, I never got this error and dunno what it's about. Table index is nil for the next function:

function LobbyManager:AddLobby(lobby) 
    if(self.lobbys[lobby]) then 
        error("Lobby "..lobby.name.." already in the manager") 
    else 
        self.lobbys[lobby] = lobby; -- < This line 
    end 
    return true; 
end 
 

Any ideas what's wrong? Thank you

Here:

function LobbyManager:DoCreateLobby(player, ...) 
    local bool = self:AddLobby(Lobby:New(player, ...)); 
    --local bool = self:AddLobby(Lobby:Constructor(player, ...)); 
    if(bool) then 
        player:ShowMessageBox(player:GetLanguage().messagebox.newgame.sucessTitle, player:GetLanguage().messagebox.newgame.sucessMessage, strings.messagebox.newgame.sucessButton, "sucess", false) 
    end 
end

The only issue I can see within your code is the following:

  
function LobbyManager:DoCreateLobby(player, ...) 
    local boolA = self:AddLobby(Lobby:New(player, ...)); 
    local boolB = self:AddLobby(Lobby:Constructor(player, ...)); 
    if(boolA) then 
        player:ShowMessageBox(player:GetLanguage().messagebox.newgame.sucessTitle, player:GetLanguage().messagebox.newgame.sucessMessage, strings.messagebox.newgame.sucessButton, "sucess", false) 
    end 
end 
 

In case you execute boolA, we've got self:AddLobby(Lobby:New()). Lobby.new returns an array (obj) which will apparently be used for indexing @self.AddLobby (self.lobbys[lobby] = lobby).

And in case you execute boolB, you'll be having nil as AddLobby's argument and consequently it will try to index self.lobbys using a nil value.
