Solved 2 Reloads to load config? Nullpointer Exception

So im making a plugin with custom configs. I have a config called "messages.yml" loading messages it will say if you for example dont have permission, for more customization.
Now the problem is that, if I delete the .yml files, and reload, it will give me some errors, BUT if I reload again after the files have been created, it loads up just fine. This is the method where im loading from config, and where it is giving me errors.:

Code:

public void noPerm(Player player) {
        String noPermMsg = messageConfig.getString("no-permission-message");
        player.sendMessage(ChatColor.translateAlternateColorCodes('&', noPermMsg));
    }

The translate alternate color codes is for color support so people can do &4 etc.. for colors in messages.

EDIT: This is my main class code:

Well, tell us the errors.

If you've deleted the file and the plugin doesn't create it after reloading and set no-permission-message then you're going to get a NPE. Do you call saveDefaultConfig() before trying to retrieve values? If so, does your default yml contain a value for no-permission-message?

 

Seems like noPermMsg is null, meaning the field no-permission-message contains nothing.

 

My messages.yml gets created before being used. The data isnt used before a player without permissions types a command. You can view all the code for the configs above in the main post.

I fixed the problem on my own. In the methods where I used the configs to get string, I added my "registerConfigs()" method, so it registers them before the getting of string. For people who will have this problem in the future, this is my registerConfigs method for my custom configs:

Code:

    public void registerConfigs() {
        logger.info("Setting up configs...");
        this.messageFile = new File(this.getDataFolder(), "messages.yml");
        this.configFile = new File(this.getDataFolder(), "config.yml");
        this.playerFile = new File(this.getDataFolder(), "players.yml");
        messageConfig = YamlConfiguration.loadConfiguration(new File(getDataFolder(), "messages.yml"));
        config = this.getConfig();
        playerConfig = YamlConfiguration.loadConfiguration(new File(getDataFolder(), "players.yml"));
        this.saveDefaultMessages();
        this.saveDefaultConfig();
        this.saveDefaultPlayers();
    }
