I’m sorry, I see it now. There is definitely a bug here, probably with the figure definition. We’ll investigate and get back to you.

thank you very much

As a workaround for now, you can redefined the “Ring” figure with this code:

go.Shape.defineFigureGenerator("Ring", function(shape, w, h) {

  var param1 = shape ? shape.parameter1 : NaN;

  if (isNaN(param1) || param1 < 0) param1 = 8;

  var rad = w / 2;

  var geo = new go.Geometry();

  var fig = new go.PathFigure(w, w / 2, true);  // clockwise

  geo.add(fig);

  fig.add(new go.PathSegment(go.PathSegment.Arc, 0.1, 360, rad, rad, rad, rad).close());

  var rad2 = Math.max(rad - param1, 0);

  if (rad2 > 0) {  // counter-clockwise

    fig.add(new go.PathSegment(go.PathSegment.Move, w / 2 + rad2, w / 2))

    fig.add(new go.PathSegment(go.PathSegment.Arc, 0, -360, rad, rad, rad2, rad2).close());

  }

  geo.spot1 = GeneratorEllipseSpot1;

  geo.spot2 = GeneratorEllipseSpot2;

  geo.defaultStretch = go.GraphObject.Uniform;

  return geo;

});

And it should fix the problem.
