Solved Load ItemStack[] from the config - NPE

hello, i want to load itemstack[]'s from the config, but there is a NPE.

Code:java

    @SuppressWarnings("unchecked")
    private void loadModes() {
        //GET FILE
        File file = new File("plugins/SimpleArena", "modes.yml");
        FileConfiguration cfg = YamlConfiguration.loadConfiguration(file);
        for (String mode : cfg.getConfigurationSection("").getKeys(false)) {
            List<ItemStack> invList = (List<ItemStack>)cfg.get(mode + "inv");
            List<ItemStack> armorList = (List<ItemStack>)cfg.get(mode + "armor");
            ItemStack[] inv = (ItemStack[]) invList.toArray();
            ItemStack[] armor = (ItemStack[]) armorList.toArray();
            this.modes.put(mode.toLowerCase(), new Mode(inv,armor));
        }
    }

Can someone help me?

 

You'll need to serialize and unserialize those ItemStacks.

 

And without serialize?
