I'm making a server side only mod that introduce a command with subcommands. One of this will give a specific item to the player, the item is defined by config. But when i run the command i get the item only the first time i run it, the next times i get nothing.

This is how i get the item

Configuration config = new Configuration(new File("config/ForgeGuard/config.cfg"));
	config.load();
	String item = config.getString("selector", "Selector Item Properties", "stick",
			"The item to use as region selector");
	String color = config.getString("color", "Selector Item Properties", "light purple",
			"The color of the name of the region selector item");
	String name = config.getString("name", "Selector Item Properties", "Region Selector",
			"The name of the region selector item");

	TextFormatting nameColor = TextFormatting.getValueByName(color);
	String displayName = "";
	if (nameColor != null)
		displayName += nameColor;
	displayName += name;
	ForgeGuard.SELECTOR = new ItemStack(Item.getByNameOrId(item), 1).setStackDisplayName(displayName);

	config.save();

 

Notice that ForgeGuard.SELECTOR is a static ItemStack declared in the main class. This code is also called from the preInit method

 

This is the command class, in the execute method i check if there are args on the command. If there are and one of this is "selector" than give the item to the player. As i said this works once but not the other times

package com.forgeguard.commands;

		if (args.length == 0) {

		} else {

					EntityItem entityitem = player.dropItem(ForgeGuard.SELECTOR, false);

					if (entityitem != null) {
						entityitem.setNoPickupDelay();
						entityitem.setOwner(player.getName());
					}
				}

				notifyCommandListener(sender, this, "commands.give.success",
						new Object[] { ForgeGuard.SELECTOR.getTextComponent(), 1, player.getName() });
			}
			/**

			else if (subcommand.equalsIgnoreCase(this.subCommands.get(1))) {

						r.setPvp(Boolean.valueOf(args[2]));
				} else
					ForgeGuard.UTILS.sendMessage(player, TextFormatting.RED + "Select a region first!");
			}
		}

	}
}

@Override
public boolean checkPermission(MinecraftServer server, ICommandSender sender) {
	boolean flag;
	if(sender.getCommandSenderEntity() == null)
		flag = true;
	else
		flag = server.getServer().getPlayerList().getOppedPlayers().getEntry(((EntityPlayer)sender.getCommandSenderEntity()).getGameProfile()) != null;
	return flag;
}

@Override
public List<String> getTabCompletionOptions(MinecraftServer server, ICommandSender sender, String[] args,
		BlockPos pos) {
	if(args[0].equalsIgnoreCase("flag") && !args[1].isEmpty())
	{
		ArrayList<String> bool = new ArrayList<String>();
		bool.add("true");
		bool.add("false");
		return bool;
	}
	if(args[0].equalsIgnoreCase("flag"))
		return this.flags;
	if(args.length > 3)
		return new ArrayList<String>();
	return this.subCommands;
}

}

 

The command is registered in the main class by doing this

@EventHandler
    public void serverLoad(FMLServerStartingEvent event)
    {
       event.registerServerCommand(new CommandRegion());
    }

 

So what could cause this issue? Thanks to all who will help me

Instead of adding ForgeGuard.SELECTOR to the inventory add ForgeGuard.SELECTOR.copy() to the inventory. I ran into this problem once. I was using the FurnaceRecipes and just straight up set the slot to the FurnaceRecipes, but then whenever I increased the stackSize I would get more for every process, and once taken out of the furnace I would get a stack of the item, but with a stackSize of zero. That was one of the best debugging moments of my life...

Thank you so much, that fixed this
