mORMot Open Source

Synopse,
  First, let me thank you for all your work on mORMot. I've had it for years, but I didn't understand it because I didn't take the time to investigate it, but recently, I've been looking to abstract the presentation layer of a Delphi program that I wrote in 2004, and I've been maintaining ever since that is tightly bound to the database engine.
  Years ago I created an owner measured and drawn DBLookupListBox alternative using large portions of the code from the DBCtrls unit. I'm not ready to completely ditch the look and feel of this in favor of the mORMot TDrawGrid just yet, so I was wondering if you'd be able to point me toward a way to connect a mORMot table to a TDatasource, or suggest some way to get the same functionality. If you paste the form components below onto a new form, you will see the general idea of my design (I changed my custom DBLookupListBox alternative into a TDBLookupListBox so that you can see what it would look like). I inherit from the form that results from the code below, and then add the functionality to communicate with the database in the descendant.
Sincerely,
Brain Cell

This code is from Delphi 2005 (which is the one that I could afford at the time)
