Nested Component and ISupportInitialize

Hi

I have a SubComponent which implements ISupportInitialize which is nested in a ParentComponent. The ParentComponent has a property (with DesignerSerializationVisibility.Content attribute) which returns the instance of sub component.

*************************Source********************************

public class ParentComponent : Component{
SubComponent _subComponent;
public ParentComponent() {
_subComponent = new SubComponent();}
[DesignerSerializationVisibility(DesignerSerializationVisibility.Content)]
public SubComponent SubComponent
{ get { return _subComponent; } }
}

[System.ComponentModel.ToolboxItem(false)]
public class SubComponent : Component, ISupportInitialize{
string _name;
public SubComponent() { }
public string Name
{get { return _name; }set { _name = value; }}
public void BeginInit() {}
public void EndInit() {}
}
**************************************************************
When I place the component on a form the code generated is

private void InitializeComponent()
{this.parentComponent1 = new ParentComponent();
((System.ComponentModel.ISupportInitialize)(this.parentComponent1.SubComponent)).BeginInit();

My problem is if I now change the name of the ParentComponent to "ParentNewName" in the properties window then the SubComponent name does not refresh and I end up with

private void InitializeComponent()
{this.ParentNewName = new SimpleComponent.ParentComponent();
((System.ComponentModel.ISupportInitialize)(this.parentComponent1.SubComponent)).BeginInit();
^^^^^^^^^^^^
