Summary0005582: JvInterpreter_Db, set TField's Value doesn't work if source value = null
DescriptionI assign Values to fields from other Dataset. These Values could be NULL, it's OK.
But null is not korrekt to assign with AsInteger.

As workaround I've changed JvInterpreter_DB, functions Write_As_XXX to work with TField.Value, not with TField.AsXXX.
Additional InformationCode Sample.
dsSMNZylinderNewEdit.Edit;
            dsSMNZylinderNewEdit.FieldByName('HerstellerID').AsInteger := dsZylinderModell.Lookup('ID', TcxCustomEdit(Sender).GetEditValue, 'HerstellerID');
                dsSMNZylinderNewEdit.FieldByName('ZylinderArtID').AsInteger := dsZylinderModell.Lookup('ID', TcxCustomEdit(Sender).GetEditValue, 'ZylinderArtID');

dsSMNZylinderNewEdit.FieldByName('LieferantID').AsInteger := dsZylinderModell.Lookup('ID', TcxCustomEdit(Sender).GetEditValue, 'LieferantID');
