Stephen,
>In the prior DDLB you didn't need to define the BindingValue(s) and I had them blank. In my case they were not lookups from a separate table.
Try setting the BindingValueSource property to something other than an empty value...it doesn't have to be a valid business object. This may get you around the problem for now.
