MutiMessage problem

Hey, I have opened this topic up many times and people have given me great responses. When I try them it doesn't really work :/

Code:

01:45:26 [SEVERE] null

Code:

    public boolean onCommand(CommandSender sender, Command cmd, String commandLable, String[] args) {
        if (!(sender instanceof Player)) {
            sender.sendMessage("Must be a player to use this command");
            return false;
        }
        if (sender.hasPermission("aura.signup")) {
            if (args.length == 0) {
                List<String> signup = plugin.getConfig().getStringList("TheAuraPack.signup");

                for(String site : signup) {

                    site = site.replaceAll("&([0-9a-fA-F])", "§$1");

                    sender.sendMessage(new StringBuilder().append(site).toString());
                }
            }
            else sender.sendMessage(ChatColor.AQUA + "You have already been promoted!");

            if (args.length > 0) {
                sender.sendMessage(ChatColor.RED + "Too many args!");
            }
        }
        return false;
    }
}

 

which line of code is 26?

 

Code:

 List<String> signup = plugin.getConfig().getStringList("TheAuraPack.signup");

 

I'm not sure... but I think it's cause the List in the config is null or it just can't find it

 

For one you are never checking what the command was. for 2 I would guess that the error is being thrown on plugin. If this is in your main class you can replace it with 'this' otherwise add a null check on it. If that isn't the problem then add a null check on plugin.getConfig()

 

does your config generate? If it doesn't thats probably your problem.

 

It wouldn't be returning an error on that line as storing null into the list is a viable option. It would be giving an error on the line that he tries to use it in the for loop.
