Shift-Clicking not filling stacks using ICraftingHandler

[Lethman427]

Hey, so I'm using a CraftingHandler to override the default planks with custom planks, but for some reason shift-clicking is acting strangely. For instance, if I only turn one log into planks, it outputs my new planks, while if I shift-click, it returns the default planks. Here's the CraftingHandler:

 

package lethman.DecayMod;

import java.util.List;

import net.minecraft.block.Block;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.inventory.IInventory;
import net.minecraft.item.ItemStack;
import net.minecraft.item.crafting.CraftingManager;

import cpw.mods.fml.common.ICraftingHandler;
import cpw.mods.fml.common.Mod;

public class PlankCraftingHandler implements ICraftingHandler
{

@Override
public void onCrafting(EntityPlayer player, ItemStack item,
		IInventory craftMatrix) 
{			
	if(item.itemID == Block.planks.blockID)
	{
		item.itemID = lethman.DecayMod.Generic.newWoodID;

		if (lethman.DecayMod.Generic.DebugLog)
			System.out.println("Overrode generic planks.");
	}			
}

@Override
public void onSmelting(EntityPlayer player, ItemStack item) 
{		
	if(item.itemID == Block.planks.blockID)
	{
		item.itemID = lethman.DecayMod.Generic.newWoodID;
	}

}

}

 

and in the mod.load():

 

                GameRegistry.registerCraftingHandler(new PlankCraftingHandler());
                OreDictionary.registerOre("plankWood", wood);                

 

Any help would be awesome.

it may be a problem with vanilla minecraft cause if you add a wood plank to the crafting bench it becomes a wooden button
