At least in IBO 4.3Aa there is a problem with firing event mentioned in
subject.

I use this event to reflect edit/insert/delete capability of query per
selected row in TIB_UpdateBar. Anyway comming from IBO3.X it's working
for years. To activate this very usefull feature (again) it's usefull to
change/uncomment line 274 in IB_UpdateBar:

procedure TIB_UpdateBar.IB_DatasetDataChange( Sender: TIB_DataLink;
DataSource: TIB_DataSource;
IB_Field: TIB_Column );
begin
; // must be defined, so it's empty since we don't use it
SysStateChanged;
end;
