Ehm, without further questions
Is this correct?
Assembly: SD.LLBLGen.Pro.DynamicDataSupportClasses.NET35.dll
Method: BuildEntityFieldProviderListAssociationsProperties()
LLBLGenProEntityFieldProvider item = new LLBLGenProEntityFieldProvider(this, descriptor2.PropertyType, false, false, false, false, 0, descriptor2.Name, **false**, relationProvider);
if the last false is always false, I think DD marks MetaColumn Required
