I think is error on CopyHostedControl

I cna create my node, can save my driagram and load again without any error.
One of my custom nodes use shape provided by BLEND.
WHen i try copy that node, have this error.
Hoppe this can e fixed ASAP.
Bets regards.

No
And no idea what is, and if neded no idea how need be config.
I google and not found nothing.
If needed i can send complete zip code example, just letmeknow.
The shape i used is ARC, from blend.
Anyway is starnge can save and lod but not copy and pase, so is a specific problem of copy.

This is really bad news, i really cant remplace ARC.  is used for a complex dynamic component cant be remplaced.

Please can explain how use iclobable, like always i request with some clete sample code?
Bets regards.

This is how i created the ARC:


var ARC = new MyARC();

var node = new DiagramNodeAdapter(form, ARC);

node.Bounds = new Rect(e.MousePosition, new Size(110, 110));

form.Nodes.Add(node);

node.Selected = true;

node.Constraints.MinWidth = 100;

node.Constraints.MinHeight = 100;

ARC.EndAngle = 90;



Now with hosted copy is how i try copy and not work:



if (e.Source is MyARC)


{


var destNode = Diagram.GetDiagramItem(e.Destination) as DiagramNodeAdapter;


var ARC = new DialCtrl();


Dial.EndAngle = ((MyARC))e.Source).EndAngle;







destNode.Control = ARC;


}



My component is already edited:
public partial class MyARC : UserControl, ISerializable, ICloneable


  public object Clone()
       {
           var clone = new MyARC();
           clone.EndAngle = this.EndAngle;
         
        
           return clone;
       }


I asumed hosted copy no is uded more, but how copy now?

Awesome is finally working !
THK !
