Saving chart with PartnerAxis set = Stack Overflow

[roumen]

VCL/FMX TeeChart ver 2017.22.170619, Delphi 10.2 Version 25.0.27659.1188

If I define 2 custom axes (horizontal and vertical) and set each to be partner axis for the other:

Code: Select all

  ax:= TChartAxis.Create(master);
  ax.Horizontal:= TRUE;
  ax.StartPosition:= 25;
  ax.EndPosition:= 75;
  ax.PositionPercent:= 25;
  ax.Title.Text:= 'Custom Horizontal';
  hax:= ax;
  ax:= TChartAxis.Create(master);
  ax.StartPosition:= 25;
  ax.EndPosition:= 75;
  ax.PositionPercent:= 25;
  ax.Title.Text:= 'Custom Vertical';
{ this causes stack overflow in syste.UnicodeFromLocakleChars: }
  ax.PartnerAxis:= hax;
  ax.UsePartnerAxis:= TRUE;
  hax.PartnerAxis:= ax;
  hax.UsePartnerAxis:= TRUE;
{}

and try to save the chart, I get stack overflow in

Code: Select all

function UnicodeFromLocaleChars(CodePage, Flags: Cardinal; LocaleStr: _PAnsiChr;
  LocaleStrLen: Integer; UnicodeStr: PWideChar; UnicodeStrLen: Integer): Integer; overload;
{$IFDEF MSWINDOWS}
begin
  Result := MultiByteToWideChar(CodePage, Flags, LocaleStr, LocaleStrLen, UnicodeStr, UnicodeStrLen);
end;
{$ENDIF MSWINDOWS}

I need PartnerAxis in order to make these custom axes movable by the mouse.
Am I doing something wrong? Any workaround?
