ComboBox CellType Error in Spread NET caused by Backspace

    I am getting the following error on a ComboBox CellType when I press the backspace key in EditMode, when the Edit
    Portion has no text in it:

    <b><i> An unhandled exception of type 'System.NullReferenceException' occurred in
    Additional information: Object reference not set to an instance of an object. </i></b>

    I'm using Microsoft visual Studio 2003 development environment and FarPoint Spread for Windows Forms 3.0.

    I'm attaching a small project where this behaviour can be verified. Is there any workaround for this issue?

    I dont have VS2003 to test the issue with. However, it got converted on VS2005 and Spread version was Spread5 beta and your sample project seems to be working fine on VS2005 and Spread5 beta, without any exception. I also tested a sample project with Spread4.0.2010.2005 and VS 2005 and set up a combo box cell type with few values in it. The backspace key is not throwing any exception with that as well.

    Could you please test the issue with latest available maintenance release of Spread? It can be downloaded from following location:
