Доброго времени. Не могу понять что не так.

Код:

unit UDocOper;

interface

uses
 messages,dialogs,SysUtils, adodb,db, windows, forms,Classes, Controls, cxControls, cxPC;

type
TopParametr = class (TCollectionItem)
private
  FDate: TDateTime;
  FCaption: string;
  FImageIndex: Integer;
  procedure SetCaption(const Value: string);
published
  property Caption: string read FCaption write SetCaption;
end;

// ---------------   тип операции документа (новый, редактирование) -----------
Type
 TTypeOperation=class (TPersistent)
 private
   FProcedureName:String;
   FParametrs:TCollection;
   Procedure SetParametrs(const Value: TCollection);
 public
    destructor Destroy; override;
    constructor Create(AOwner: TComponent);
 published
   property ProcedureName:string read FProcedureName write FProcedureName;
   property Parametrs:TCollection read FParametrs write FParametrs;

end;

//---------------------  форма документа ---------------------------------------
type
 TDocumentOperation = class(TComponent)
 private
   FopInsert:TTypeOperation;
   Procedure Setpoperation(value:TTypeOperation);
 protected
 public
   constructor Create(AOwner: TComponent); override;
   destructor Destroy; override;
 published
   property opInsert:TTypeOperation read FopInsert write Setpoperation;
 end;

procedure Register;

implementation

procedure Register;
begin
 RegisterComponents('CxDataControls', [TDocumentOperation]);
end;

{ TTypeOperations }

procedure TopParametr.SetCaption(const Value: string);
begin
FCaption := Value;
end;

////////////////////////////////////////////////////////////////////////////////
constructor TTypeOperation.Create(AOwner: TComponent);
begin
  FParametrs:=TOwnedCollection.Create(Self, TopParametr);

end;

destructor TTypeOperation.Destroy;
begin
 inherited;
  FreeAndNil(FParametrs);
end;

procedure TTypeOperation.SetParametrs(const Value: TCollection);
begin
FParametrs.Assign(Value);
end;

{ TDocumentOperations }

constructor TDocumentOperation.Create(AOwner: TComponent);
begin
 inherited;
  FopInsert:=TTypeOperation.Create(self);
end;

destructor TDocumentOperation.Destroy;
begin
 inherited;
 FreeAndNil(FopInsert);
end;

procedure TDocumentOperation.Setpoperation(value: TTypeOperation);
begin
 FopInsert:=value;
end;

end.

В итоге при инсталляции компонента у свойства Parametrs не отображается редактор
