	hi there, i was wondering how could i set the link of a newly created node onto an existing node here is my code so far : Code (Javascript) nodes.forEach((node) => { const newNode = new mf.Diagramming.SvgNode(this.state.diagram); newNode.setAnchorPattern(pattern); newNode.getBounds().x = boundx; newNode.getBounds().y = boundy + 40; this.state.diagram.addItem(newNode); //var Link = new mf.Diagramming.DiagramLink(newNode, node); //this.state.diagram.addItem(Link); } the code can make a new node below already existing node but the commented part gave me an error and won't create a link between them, how do i do it?

	Hi, Pass the diagram as first argument of item constructors, including link's one. You could call diagram.factory.createDiagramLink(node1, node2) instead of constructor and addItem. Regards, Slavcho Mindfusion

	Yes, or diagram.getFactory() for version 3 API.
