The code generation project Prometheus continues to evolve.  I have the general ASP.NET UI generation completed.  However as I move forward there are some advanced features to add.  One of these is support for lists.  DropDownLists or ListBox controls are the first and foremost issue.  It's fine to generate them but the current issue is how to indicate the datasource for the values to populate the list.  This is more of a conceptual problem then a technical problem as I know serveral ways to do this but I need to determine a nice clean way to make this work with the rest of the site.
