Save an inventory in config > ERROR

I need to save a inventory in the config and it is working, but if I reload or open again ther Server an ERROR appears at the Console:

The Config:

Code:

JackpotInventory:
  CruzAPI: !!org.bukkit.craftbukkit.v1_7_R4.inventory.CraftInventoryCustom
    contents:
    - null
    - null

    maxStackSize: 64

Line 36 (ERROR):

Code:

        Jackpot = YamlConfiguration.loadConfiguration(JackpotFile);

And after this error the config is reseted!
I don't know what is it, and I need help. Thanks

My Main:

Main (open) Main (close)

Jackpot = YamlConfiguration.loadConfiguration(JackpotFile);

}
}

 

You try to serialize an inventory, that's not possible, you need to serialize the contents separately (itemstack is serializable), then load it back.

 

Thanks! I did it, but another error appears:

When i stop or reload the server the Bukkit can't read the ItemStack[] in the config, showing an error in console.

The error:

The line:

Line 51 (open) Line 51 (close)

ItemStack[] items = (ItemStack[])Main.Jackpot.get("JackpotInventory." + p.getName());

 

This error happens, because you get a collection from the config, not an array, and you try to cast it to that.

 

OK, I tried to get the itens changing the line 51 to:

Code:

List<ItemStack> items = (List<ItemStack>)Main.Jackpot.get("JackpotInventory." + p.getName());

But the error of ClassCastException persistis...

What i have to do? I have to change (List<ItemStack>) to....?

 

You get a String List the config, you need to serialize and deserialize the itemstacks one by one.

 

Code:

Object items = Main.Jackpot.get("JackpotInventory."+ p.getName());
ItemStack[] inventory = null;
      
if (items instanceof ItemStack[]) {
            inventory = (ItemStack[]) items;
} else if (items instanceof List) {
            List<?> listitems = (List<?>) items;
            inventory = (ItemStack[]) listitems.toArray(new ItemStack[0]);
}

 

Thanks

 

1.: Please don't spoonfeed
2.: This is one of the worst code snippets I've ever seen.

 

At least it works...

 

At least ot works isbthe laziest sentence in programming, facebook actually fires people if they create code that "just works"

 

Lucky this is just Bukkit and not Facebook then, isn't it.

 

@mcdorli
I'm sure Facebook wouldn't mind if you created an obedient, sentient, and omnipotent program in a roundabout way and said "at least it works."
