When I click on a box and move, instead of moving, it is making a copy of the box

GoJS

Hi,

I have set below properties but it does not help me.

this.myDiagram.allowCopy = false;

this.myDiagram = this.make(go.Diagram, this.element.nativeElement,
{
initialContentAlignment: go.Spot.Center, // center the content
“toolManager.mouseWheelBehavior”: go.ToolManager.WheelZoom,
‘undoManager.isEnabled’: true, // enable undo & redo
"draggingTool.isCopyEnabled": false,
mouseOver: (e) => this.doMouseOver(e), // this event handler is defined below
click: (e) => this.doMouseOver(e) // this event handler is defined below
});

Please give your suggestion.

Did you set Diagram.allowCopy before replacing the whole Diagram?

What properties have you set on the Node?

What does your doMouseOver function do?

Below is the my code sequence.
And doMouseOver just used to show tooltip.

this.myDiagram = this.make(go.Diagram, this.element.nativeElement,
{
initialContentAlignment: go.Spot.Center, // center the content
“toolManager.mouseWheelBehavior”: go.ToolManager.WheelZoom,
‘undoManager.isEnabled’: true, // enable undo & redo
“draggingTool.isCopyEnabled”: false,
mouseOver: (e) => this.doMouseOver(e), // this event handler is defined below
click: (e) => this.doMouseOver(e) // this event handler is defined below
});

var that = this;
this.myDiagram.addDiagramListener("ObjectSingleClicked", function (ev) {
  that.GetTaskDetails(ev);
});

this.myDiagram.isReadOnly = false;
this.myDiagram.allowDrop = true;
this.myDiagram.allowDragOut = true;
this.myDiagram.allowReshape = true;
**this.myDiagram.allowCopy = false;**
this.myDiagram.allowMove = true;
this.myDiagram.allowZoom = true;
this.myDiagram.undoManager.isEnabled = true;

A minor point about code style: you could have set all of those Diagram properties, and the “ObjectSingleClicked” DiagramEvent listener, in the initialization of the Diagram.

Please could show us a way to reproduce the problem? I’m unable to do so with the information that you’ve given so far.
