FormatString handling in numeric updowns

[omariom]

Most of the code assumes that FormatString is not null. If FormatString is null it starts throwing NullReferenceExceptions. Null value can be assigned if the bound property returns null.

I think, it should be handled in OnCoerceFormatString. As an example:

private static object OnCoerceFormatString(DependencyObject d, object baseValue)
{
    return baseValue ?? "";
}

Hi,

Thank you for reporting this. It will be fixed in v3.8.

I think, this issue can be closed as it's already released at part of v3.8.
