Link text on Hierarchical Diagram?

GoJS
1

Is it possible to create link text on hierarchical diagrams, because I’m not explicitly creating the links… ? Here is my code:

    var $ = go.GraphObject.make;

    var myDiagram =
        $(go.Diagram, this._element.nativeElement,
            {
                initialContentAlignment: go.Spot.TopCenter, // center Diagram contents,
                "isReadOnly": true,
                "undoManager.isEnabled": true, // enable Ctrl-Z to undo and Ctrl-Y to redo
                layout: $(go.TreeLayout, // specify a Diagram.layout that arranges trees
                    { angle: 90, layerSpacing: 35 })
            });

    // the template we defined earlier
    myDiagram.nodeTemplate =
        $(go.Node, go.Panel.Auto,
        $(go.Shape, "Hexagon",
            { fill: "lightgrey" , angle: 90},
            new go.Binding("figure", "fig"),
            new go.Binding("fill","color")
        ),
        $(go.TextBlock, 
            { margin: 15, },
            new go.Binding("text", "name"))
        );

    // define a Link template that routes orthogonally, with no arrowhead
    myDiagram.linkTemplate =
        $(go.Link,
            { routing: go.Link.Orthogonal, corner: 5 },
            $(go.Shape, { strokeWidth: 3, stroke: "#555" }),
            $(go.TextBlock,
                {
                    textAlign: "center",
                    font: "14pt helvetica, arial, sans-serif",
                    stroke: "#555555",
                    margin: 4 
                },
                new go.Binding("text","text"))
        ); // the link shape

    var model = $(go.TreeModel);
    
    model.nodeDataArray =
        [
        { key: "1", name: this.cpm.decisions[0].label, fig: "Hexagon", color: "lightgrey",text:"link text here" },
        { key: "2", name: this.cpm.decisions[1].label, parent: "1", fig: "Hexagon", color: "lightgrey" },
        { key: "3", name: this.cpm.decisions[2].label, parent: "1", fig: "Hexagon", color: "lightgrey" },
        { key: "4", parent: "3", name: "TODO", fig: "Hexagon", color: "lightgrey" },
        { key: "5", parent: "3", name: "TODO", fig: "Hexagon", color: "lightgrey" },
        { key: "6", parent: "2", name: "TODO", fig: "Hexagon", color: "lightgrey" }
        ];
    myDiagram.model = model;

Node “1” doesn’t have a parent, so there’s no parent Link, so you don’t get to see any TextBlock whose TextBlock.text was data bound to the node’s data.text property.

Doh, thanks!
