Cannot access component's object properties in design time

I'm fairly [b]new[/b] to building components. I'm trying to use another custom object as a property in the component, but in design time the component's object properties which I'm trying to use are not working; that is, when I click on the [+] in the Object Inspector, nothing expands, and sometimes I get an error. I'm creating these objects on component's creation, and assigning the owner. The objects store various other properties. Everything works fine in run time, just not design time. Perhaps I'm declaring something wrong? I've also tried using TComponent as the inherited type, but still didn't work, actually got more errors.

[b]How I'm doing it:[/b]

(wrote the code here, didn't copy/paste it, so may be minor mistakes)


unit MyCustomComponent;


SysUtils, Classes, Controls, ComCtrls, Forms, Graphics, DB, ADODB;

TMyComponent = class;

TMyType = (myType1, myType2, myType3);

TMyObject = class(TObject)
Number: Integer;
Text: String;
SomeOtherObject: TObject;
MyType: TMyType;

TMyComponent = class(TComponent)
FMyObject: TMyObject;

constructor Create(AOwner: TComponent); override;
destructor Destroy; override;

property MyObject: TMyObject read FMyObject;


procedure Register;


procedure Register;
RegisterComponents('My Custom Components',[TMyComponent]);

constructor TMyComponent.Create(AOwner: TComponent);
inherited Create(AOwner);
FMyObject:= TMyObject.Create;

destructor TMyComponent.Destroy;
if assigned(FMyObject) then FMyObject.Free;
inherited Destroy;
