Jason,

I got bitten by a little problem in TIB_ControlDataLink and I'm
checking whether my fix is not going to brake something else.

I'll try explaining my problem using these objects:

MyObject: TIB_FieldDataLink;
MyWinControl: TWinControl;

TIB_FieldDataLink = class(TIB_ControlDataLink)
TIB_ControlDataLink = class(TIB_InterfaceDataLink)
TIB_InterfaceDataLink = class(TIB_DataLink)

MyObject.Control = MyWinControl;
TIB_InterfaceDataLink(MyObject).Control = nil;

Same object has 2 different values in the "same" property.

I say "same" because it is not really the same.

This is an extract from the definition:

TIB_InterfaceDataLink = class(TIB_DataLink)
private
FControl: TWinControl;
public
property Control: TWinControl read FControl write FControl;
end;

TIB_ControlDataLink = class(TIB_InterfaceDataLink)
private
FControl: TWinControl;
public
property Control: TWinControl read FControl write FControl;
end;


My question is why? Is this on purpose or is it a mistake? Should I
remove the property from TIB_ControlDataLink or
TIB_InterfaceDataLink?

Cheers,
