[1.7.2] Netty Packet doesn't decode on server side

i'm having a problem with the new netty system where i can send a packet in singleplayer without any problems but when i try on a local server (using ip: localhost) it seams that the client sends and encode the packet but it never run the decode or handleServerSide code's

the packet i'm trying to send

package com.dark2222.vampiremod.core.PacketHandler.packets;
import io.netty.buffer.ByteBuf;
import io.netty.channel.ChannelHandlerContext;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.entity.player.EntityPlayerMP;
import net.minecraft.util.ChatComponentText;
import net.minecraft.util.IChatComponent;

import com.dark2222.vampiremod.core.VampireMain;
import com.dark2222.vampiremod.core.BloodCore.BloodCore;
import com.dark2222.vampiremod.core.BloodCore.TickHandler;
import com.dark2222.vampiremod.core.PacketHandler.AbstractPacket;

import cpw.mods.fml.common.gameevent.TickEvent;
import cpw.mods.fml.common.network.ByteBufUtils;
public class FoodPack extends AbstractPacket{
int i;

public FoodPack() {}

public FoodPack(int i){
	this.i = i;
}

@Override
public void encodeInto(ChannelHandlerContext ctx, ByteBuf buffer) {
	buffer.writeInt(i);
}

@Override
public void decodeInto(ChannelHandlerContext ctx, ByteBuf buffer) {
	i = buffer.readInt();
}

@Override
public void handleClientSide(EntityPlayer player) {
		System.out.print("Running Client ");
		BloodCore props = BloodCore.get(player);

}

@Override
public void handleServerSide(EntityPlayer player) 
{	
		System.out.print("Running server ");
		BloodCore props = BloodCore.get(player);
}

}

my packetpipeline class is just "copy-paste" from the tutorial as is the abstractPacket class

i register the packages in the packetpipeline
