This is what I am using to retrieve the inventory from the config

Code:java

 
Inventory inv = Bukkit.createInventory(player, 27, ChatColor.GOLD + "Fanny Pack");
if(this.getConfig().contains(player.getUniqueId() + ".FannyPack")){
inv.setContents(((ItemStack[]) this.getConfig().get(player.getUniqueId() +".FannyPack")));
player.openInventory(inv);
} else
player.openInventory(inv);

This is what I am using to save the inventory

Code:java

 
@EventHandler
public void InvClose(InventoryCloseEvent event){
if(event.getInventory().getTitle().equalsIgnoreCase(ChatColor.GOLD + "Fanny Pack")){
this.getConfig().set(event.getPlayer().getUniqueId() + ".FannyPack", event.getInventory().getContents());
this.saveConfig();
}
}

Also just to clarify when I get that error it won't even open a blank inventory

I have tried saving the whole inventory instead of just the contents but I just got the same problem (though it did open a blank inventory when I got the error)

EDIT: Almost forgot, this is what is on line 103

Code:java

inv.setContents(((ItemStack[]) this.getConfig().get(player.getUniqueId() +".FannyPack")));

 

monkeymanboy what does your config look like after saving the inventory?

 

Code:

db599ec0-c74f-33c1-a8ab-b00550defb5c:
  FannyPack:
  - ==: org.bukkit.inventory.ItemStack
    type: DIRT
    amount: 60
  - null

Nothing changes in it when I reload

monkeymanboy You are trying to cast an ArrayList to an ItemStack[], use http://docs.oracle.com/javase/7/docs/api/java/util/List.html#toArray(T[]) to convert it from a List to an array

 

I tried using a for loop going through ItemStack[] then adding each one to the inventory then it gave me the same problem, also it doesn't give me the problem until I reload or restart which is kinda weird

Did you try what xTigerRebornx suggested?

You're going to get a List from the Configuration, you have to convert it to an array, you can't just cast it.

I did this

Code:java

 
List<ItemStack> Inv = (List<ItemStack>) this.getConfig().getList(player.getUniqueId() + ".FannyPack");
inv.setContents(Inv.toArray(new ItemStack[0]));

Now I can open it but then I can't if I try again (I get a null pointer exception and it says on the setContents line) but if I reload I can open it one more time then it continues the problem

 

Code:java

new ItemStack[0]

This should have the size of your list, not 0

 

I put Inv.size() instead of 0 and I get the same error

 

monkeymanboy If you are getting an NPE, then

Code:

this.getConfig().getList(player.getUniqueId() + ".FannyPack")

Is returning null. Debug some, find out what is null, what you are inputting, etc

 

I don't know what it could be especially since it works once per reload/restart

monkeymanboy What was the result of when you debugged?

 

I don't know how I would go about debugging this

 

monkeymanboy Print out things. Things I would print out: The List, the Player's UUID
Also, print out some simple debug lines to see if your 'set' code is reached in your InventoryCloseEvent listener

 

I'll try that

xTigerRebornx I couldn't figure it out but I did try saving it a bit differently and this worked.

Code:java

 
                        Inventory inv = Bukkit.createInventory(player, 27, ChatColor.GOLD + "Fanny Pack");
                        if(this.getConfig().contains(player.getUniqueId() + ".FannyPack")){
                            for(int i=0; i<26; i++){
                                if(this.getConfig().contains(player.getUniqueId() + ".FannyPack." + i)){
                                    inv.setItem(i, this.getConfig().getItemStack(player.getUniqueId() + ".FannyPack." + i));
                                }
                            }
                            player.openInventory(inv);
                        } else{
                            player.openInventory(inv);
                        }
                    }
                }
    }
    @EventHandler
    public void InvClose(InventoryCloseEvent event){
        if(event.getInventory().getTitle().equalsIgnoreCase(ChatColor.GOLD + "Fanny Pack")){
            int i = 0;
            for(ItemStack im : event.getInventory().getContents()){
                this.getConfig().set(event.getPlayer().getUniqueId() + ".FannyPack." + i, im);
                i = i + 1;
            }
            this.saveConfig();
        }
    }
