Invalid FORMATETC structure (Exception from HRESULT: 0x80040064(DV_E_FORMATETC))

Now I've tried to create my own class library and reference it, when I drag
and drop a control (Basket) from the library in VS.Net 2005 I get the error:
Invalid FORMATETC structure (Exception from HRESULT:
0x80040064(DV_E_FORMATETC))
The code in the class library is:
Basket.cs:
----------
using System;
using System.Collections.Generic;
using System.Text;
using System.Web;
using System.Web.UI;
using System.ComponentModel;
namespace WebUI.Basket
{
[ParseChildren(true)]
class Basket : Control, INamingContainer
{
//public void Basket() { }
private ITemplate _headerTemplate = null;
[TemplateContainer(typeof(BasketHeader))]
public ITemplate Header
{
get
{
return _headerTemplate;
}
set
{
_headerTemplate = value;
}
}
// override to prevent literal controls from being added as children
protected override void AddParsedSubObject(object o)
{
}
protected override void CreateChildControls()
{
// if (Header != null)
// {
// create header
BasketHeader header = new BasketHeader();
// initialize header from template
Header.InstantiateIn(header);
// add header to the child controls collection
Controls.Add(header);
header = new BasketHeader();
// initialize header from template
Header.InstantiateIn(header);
// add header to the child controls collection
Controls.Add(header);
//}
}
}
}

BasketHeader.cs:
---
using System;
using System.Collections.Generic;
using System.Text;
using System.Web;
using System.Web.UI;
using System.ComponentModel;
namespace WebUI.Basket
{
class BasketHeader : Control, INamingContainer
{
}
}

Can anyone help me with this?
Kind Regards,
