PropertyGrid doesn't load correct float[] property values

I have a strange problem.
I have defined a windows component class in which there is a float [] private member like this:


private float [] m_Directions = new float[] {0,1,2};

Then I have created a property for setting and retrieving values of such a member, with designer support, like this:

[
Browsable(true),
Category("Blend settings")
]
public float[] Directions
{
get
{
return m_directions;
}
set
{
m_directions = value;
}
}

When I am in design mode, setting of float[] goes well, (and I find updated values in InitializeComponent() method. Correct!

When I shutdown .NET Devenv and then reopen my project, designer doesn't load
the last values for m_Directions array, but the old ones {0,1,2}. Why?
Is there a way to tell designer to load values from InitializeComponent() method?

Any idea?
thank you very much in advance!

Does this happen at runtime as well?

No, at runtime everything is correct.
I would like to tell designer to reload new values when devent loads, from InitializeComponents(), ... but how?

Does this make any difference?

Code:

---

[
Browsable(true),
Category("Blend settings")
]
public float[] Directions
{
    get
    {
        return m_directions;
    }
    set
    {
        m_directions = value;
      Invalidate();
    }
}

If not can you post (or email) a complete component?

Same problem. This is my component (a simple Panel):

using System;
using System.ComponentModel;
using System.Collections;
using System.Diagnostics;

namespace WinApp
{
/// <summary>
/// Summary description for MyPanel.
/// </summary>
public class MyPanel : System.Windows.Forms.Panel
{
private float [] m_directions = new float[]{0,0,1};
/// <summary>
/// Required designer variable.
/// </summary>
private System.ComponentModel.Container components = null;

public MyPanel(System.ComponentModel.IContainer container)
{
///
/// Required for Windows.Forms Class Composition Designer support
///
container.Add(this);
InitializeComponent();

//
// TODO: Add any constructor code after InitializeComponent call
//
}

public MyPanel()
{
///
/// Required for Windows.Forms Class Composition Designer support
///
InitializeComponent();

//
// TODO: Add any constructor code after InitializeComponent call
//
}

/// <summary>
/// Clean up any resources being used.
/// </summary>
protected override void Dispose( bool disposing )
{
if( disposing )
{
if(components != null)
{
components.Dispose();
}
}
base.Dispose( disposing );
}


#region Component Designer generated code
/// <summary>
/// Required method for Designer support - do not modify
/// the contents of this method with the code editor.
/// </summary>
private void InitializeComponent()
{
components = new System.ComponentModel.Container();
}
#endregion

[
Browsable(true),
Category("Blend settings")
]
public float[] Directions
{
get
{
return m_directions;
}
set
{
m_directions = value;
Invalidate();
}
}
}
}

I found a MS Article about a similar problem with double array...

http://support.microsoft.com/default...b;EN-US;832924

In fact 2 minutes ago I noticed the following error at design time:

" At least one element in the source array could not be cast down to the destination array type."

I noticed the design time error message as well.

I know the bug report mentions some workarounds, but Instead of using float/double you could also use int and express your values as percentages.
