                                    Since I upgraded to 18.2.3 (previous was 18.1.8 IIRC) I have a EVariantTypeCastError when inserting a new record in cxEdit, line 9038, procedure TcxCustomEditProperties.DoValidate :

                                    AIsUserErrorDisplayValue := not InternalCompareString(APrevDisplayValue, ADisplayValue, True);

                                    Since the field is NULL (just inserted and no default value) the DisplayValue is NULL and the Exception is triggered.

                                    I guess this has to do with T669565

                                    Am I doing something wrong ?

                                  Here it is. Either scroll to the last line or select the DBGrid and press Insert.
