ListConverter Bug

I am using

 

IdeaBlade 3.6.2.2

VS 2008

Infragistics NetAdvantage for .net 2008 Vol 1

 

I have done my work, I am 100% sure that its because of IdeaBlade, the application crashes in the Infragistics code but only when the contol is bound through ListConverter, when the control is bound through .net databinding no exception occurs. I found that display of "(none)" for null value is creating the problem.

 

Here I am attaching my sample project which I have created to produce that bug, its a simple project no DB is required.

 

Download here Sample Project (http://www.ideablade.com/forum/uploads/382/ComboProblem.zip)

 

Steps to produce:

 

Run the application, there are 3 items in the Binding Navigator, navigate to the last one, make sure that the focus is on the ultracomboeditor control(by default if you don't click on the form and navigate to the last one, this control should have the focus).

 

Once you are on the last item, hit the delete button on the binding navigator and you will have the exception:
