I'm not exactly sure how to ask my question, so I apologize in advance.

I am trying to create an item that functions as a container but the itemID (image) is something else entirely. Example, if I wanted the image of a table to function as a container and open a container gump when double clicked.

Here is portions of the code I have below. My problem is, when I reference the base for a chest or other actual container, everything works fine. When I change my base to that of a table for instance, the interaction breaks.

Code:
using Server;
using Server.Items;
using Server.Multis;
using Server.Network;
using Server.Mobiles;
using System;


namespace Server.Items
{

    [FlipableAddon(Direction.South, Direction.East)]
    public class MyContainerAddon : BaseAddonContainer
    {
        [Constructable]
        public MyContainerAddon() : base( 0x0ED5 )
        {
            Name = "MyContainer";
            Movable = false;
        }

        public override int DefaultGumpID
        {
            get
            {
                return 0x2658;
            }
        }

        public override void OnDoubleClick(Mobile from)
        {
        }

        public MyContainerAddon(Serial serial) : base(serial)
        {
        }

        public override void Serialize(GenericWriter writer)
        {
            base.Serialize(writer);

            writer.Write((int)0); // version
            writer.Write(m_Owner);  //Save the owner
        }

        public override void Deserialize(GenericReader reader)
        {
            base.Deserialize(reader);

            int version = reader.ReadInt();
            m_Owner = reader.ReadMobile();
        }
    }
}

This is the script I am getting my inspiration from. The same thing happens when I change the base of this script to that of a table, the object stops acting like a container.

Code:
//Safety Deposit Box
//RunUO 2.0 Final & RunUO SVN
//By DxMonkey aka Tresdni & Fenris
/*
Simply place these around banks.  They are unmovable and show if they are unclaimed or not.  When a player double clicks
the box, and has enough to purchase it, the box will be assigned to them, and will open for them ONLY.  The purchase type
can be changed easily where marked.  It is set as default for 5,000 gold.

It must inherit BaseContainer, otherwise it will fail.
As for changing the interaction with a different graphic, i think it should work regardless of the itemid.
 
In my experience, a container must use a container image. Chests, boxes, baskets, drawers, anything that originally acted as a container.
