How to create a config list ?

Hi,
first, I am pretty new at bukkit developing..
I want to create a simple config file. In this config file, i want to create a list like:

Code:

#Config
List:
    -this
    -is
    -a
    -list

I have a command "addtolist". When i type "/addtolist test", 'test' should be added to my list.
I red the config tutorial and tried to get it to work ..

Code:

        @Override
        public boolean onCommand(CommandSender sender, Command cmd, String label, String [] args) {
            if(sender instanceof Player) {
                Player player = (Player)sender;
               
                if(cmd.getName().equalsIgnoreCase("addtolist")) {
                    if(args.length > 1) {
                        return false;
                    }
                    if(args.length == 0) {
                        return false;
                    }
                    if(args.length == 1) {
                        plugin.getConfig().getList("List").add(args[0]);
                        plugin.saveConfig();
                        plugin.reloadConfig();
                        player.sendMessage("Done");
                        return true;
                    }
                }
            }
            return false;
        }
}

But eclipse says that

Code:

 plugin.getConfig().getList("List").add(args[0]);

is wrong.
It underlines 'add'

Sorry for my bad english. I hope you guys understand.

 

LunaTiX_ It doesn't know the type of the list. You'll probably need to cast it, something like

Code:

        @SuppressWarnings("unchecked")
        List<String> blah = (List<String>) this.getConfig().getList("List");
        blah.add("lala");

or just

Code:

((List<String>) this.getConfig().getList("List")).add("lala");

 

Hi,
Thanks for your answer.
Now my command looks like this:

Code:

                if(cmd.getName().equalsIgnoreCase("addtolist")) {
                    if(args.length > 1) {
                        return false;
                    }
                    if(args.length == 0) {
                        return false;
                    }
                    if(args.length == 1) {
                        ((List<String>) plugin.getConfig().getList("List")).add(args[0]);
                        plugin.saveConfig();
                        plugin.reloadConfig();
                        player.sendMessage("Done");
                        return true;
                    }
                }

I started my server and test it. I got an internal server error:

Code:

configList.add(args[0]);
plugin.getConfig(),set("List", configList);
