it called once for one table but if i understand your code,

procedure TD.Loaded;

begin

  inherited;

  dec(FCellCount);

  if FCellCount=0 then

    FRVTableSW.Free;

end; // HERE self (the TD object) does not exists because

TRVTableSW.Destroy destroy it when FCellCount=0 ? in Delphi, an object

can't destroy itself.

constructor TRVTableSW.Create(AOwner: TComponent);

begin

  inherited Create(AOwner);

  FTD := TD.Create(nil);

  FTD.FRVTableSW := Self;

end;

destructor TRVTableSW.Destroy;

begin

  FTD.Free;

  inherited Destroy;

end;
