Can't get Connector Rounded Corners to display

I am generating a diagram in code.  I add two rounded rectangles and then connect them with an OrthogonalConnector.  I set the EnableRoundedCorners to true and the curveRadius to 10 (or anything).  But, the diagram shows a crisp 90 degree corner.  Here is he code I am using to create the connector:

   private PathNode ConnectNodes(PathNode n1, PathNode n2)
            OrthogonalConnector c1 = new OrthogonalConnector(n1.PinPoint, n2.PinPoint);
            c1.EnableRoundedCorner = true;
            c1.CurveRadius = 10;

            c1.HeadDecorator.DecoratorShape = DecoratorShape.FilledCircle;
            c1.HeadDecorator.Size = new SizeF(ARROW_HEAD_SIZE, ARROW_HEAD_SIZE);
            c1.TailDecorator.DecoratorShape = DecoratorShape.FilledFancyArrow;
            c1.TailDecorator.Size = new SizeF(ARROW_TAIL_SIZE, ARROW_TAIL_SIZE);
            c1.LineStyle.LineColor = ARROW_DEFAULT_COLOR;
            c1.LineStyle.LineWidth = ARROW_LINE_WIDTH;

            return c1;


What am I doing wrong?  Thanks.

Thank you for the reply.  When I try your sample, it does work.  

Apparently, the issue is that when LineBridging is enabled (in the property editor), rounding does not work.  Using:

myDiagram.Model.LineBridgingEnabled = false;

Makes the rounded corners work correctly.

Is this a bug or intended behavior?

Thanks very much for your help.
