Cannot read properties of undefined (reading 'visible') in Diagram component

[Alex B]

Hi Syncfusion

I'm using diagram component + Tree View with enabled drag&drop.
I'm dragging elements from Treeview into diagram with using nodeDragStop event.
The handler is:

    existingTableDropped(args: DragAndDropEventArgs) {

        let targetEle: any = closest(args.target, ".e-droppable");

        targetEle = targetEle ? targetEle : args.target;

        // check an target as diagram

        if (targetEle.classList.contains("e-diagram")) {

            let data: any = args.draggedNodeData;

            let node = {} as NodeModel;

            let id =

                data.parentID == EntityType.Table

                    ? `DbTable${data.text}`

                    : data.parentID == EntityType.Dbview

                    ? `DbView${data.text}`

                    : "";

            let cssClass =

                data.parentID == EntityType.Table

                    ? "table-node"

                    : "dbview-node";

            node.id = id;

            node.shape = {

                type: "HTML",

                content: getNodeTemplate(cssClass, data.text),

            };

            node.height = 30;

            node.width = 230;

            node.offsetX = args.event.offsetX;

            node.offsetY = args.event.offsetY;

            let annotation: ShapeAnnotationModel[] = getAnnotationModel(

                data.text

            );

            node.annotations = annotation;

            //add an node at runtime

            this.diagramInstance.add(node);

            // Remove the treeview node after add the node in diagram

            args.clonedNode.remove();

        }

    }

Then on drag I get an error and I can't see treeview element under cursor during drag, but node is correctly created.

Hi Alex,

We have created a sample in which we can drag a treeview element into a diagram. Please refer to the sample below. Please upgrade to the latest version (v20.2.45) packages of the diagram to resolve the reported issue.

Regards,
