Custom ColorGrid palette lost

TeeSurfa.pas rev 1.36 (TeeChart v2014.10) introduced property IDirtyPalette that seems to break the palette the user defines in the example attached.

Here it is a possible fix, adding an "if" to TCustom3DPaletteSeries.NotifyValue

Procedure TCustom3DPaletteSeries.NotifyValue(ValueEvent:TValueEvent; ValueIndex:Integer);
begin
  inherited;
  if ValueEvent=veClear then
    IDirtyPalette:=True;
end;

A better fix would probably be in TCustom3DPaletteSeries.CheckPaletteEmpty, changing this:

Procedure TCustom3DPaletteSeries.CheckPaletteEmpty;
begin
  if (Count>0) and ( (Length(FPalette)=0) or IDirtyPalette ) then
     CreateDefaultPalette;
end;

For this:

Procedure TCustom3DPaletteSeries.CheckPaletteEmpty;
begin
  if (Count>0) and ( (Length(FPalette)=0) or not IDirtyPalette ) then
     CreateDefaultPalette;
end;
