I tried to save an Entity as NBTTagCompound and then create a new Entity from that NBTTagCompound when hitting an Entity with my item. This is what i have:

	@Override
	public boolean onLeftClickEntity(ItemStack stack, EntityPlayer player, Entity entity) {
		if (!player.world.isRemote ) {
			NBTTagCompound ttt = entity.writeToNBT(new NBTTagCompound());
			Entity eee = EntityList.createEntityFromNBT(ttt, player.world);
			if (eee != null) {
				eee.setPosition(player.posX, player.posX, player.posX);
				player.world.spawnEntity(eee);
			}
		}
		return true;
	}

But i just get this:

[minecraft/EntityList]: Skipping Entity with id minecraft:
