Gates connecting to custom Wall

[LePheel]

I'm trying to code a custom wall based off the cobblestone walls. I can't seem to get Fence Gates to interact properly with it, however. The gates seem to be unchanged, as if connecting to a fence post. The wall responds to the presence of the gate, but the gate doesn't "lower" like it does with cobble walls.

 

 

Wall Code:

package com.lepheel.alamor.blocks;

import java.util.List;

import net.minecraft.block.BlockWall;
import net.minecraft.client.renderer.texture.IIconRegister;
import net.minecraft.creativetab.CreativeTabs;
import net.minecraft.init.Blocks;
import net.minecraft.item.Item;
import net.minecraft.item.ItemStack;
import net.minecraft.util.IIcon;

public class BlockLogPostBlock
  extends BlockWall{
  public BlockLogPostBlock(){
    super(Blocks.log);
    setCreativeTab(CreativeTabs.tabBlock);
  }
     
@SuppressWarnings({ "unchecked", "rawtypes" })
public void getSubBlocks(Item par1, CreativeTabs par2CreativeTabs, List par3List)
{
             par3List.add(new ItemStack(par1, 1, 0));
     }
@Override
public IIcon getIcon(int par1, int par2)
{
	return Blocks.log.getBlockTextureFromSide(par1);
}

  public void registerBlockIcons(IIconRegister par1IconRegister){
    this.blockIcon = par1IconRegister.registerIcon("Alamor:" + getUnlocalizedName().substring(5));
  }
}

Any suggestions?
