I tried the following and i'm getting the EOleError 'Object factory for
class TActionItem missing'.
program FWTest02;
{$APPTYPE CONSOLE}
uses
ExceptionLog,
SysUtils
, ComObj
;
type
IActionItem = interface
function GetName : String;
end;
TActionItem = class(TComObject, IActionItem)
function GetName : String;
end;
var
ai : IActionItem;
{ TActionItem }
function TActionItem.GetName: String;
begin
Result := 'ActionItem';
end;
begin
ai := TActionItem.Create;
writeln(ai.GetName);
end.

Inherit from TInterfacedObject NOT from TComObject. TComObject will
require you to initialize the COM subsystem of Windows -- which is a
waste since you're just using your interfaces internally.
