Q1:Can there be multiple links between two nodes?Like this ：
Q2：I set toMaxLinks and fromMaxLinks equal to 1000, but the link between two nodes can only be connected once.
var gnTemplate =
g_(go.Node, "Auto",
{ selectionAdorned: true,
resizable: true,
//layoutConditions: go.Part.LayoutStandard & ~go.Part.LayoutNodeSized,
portId: "1",
toMaxLinks:1000,
fromMaxLinks:1000,
fromLinkable: true,
toLinkable: true
//fromSpot: go.Spot.AllSides,
//toSpot: go.Spot.AllSides
},
new go.Binding("angle","angle").makeTwoWay(),
new go.Binding("category","category").makeTwoWay(),
new go.Binding("location","loc",go.Point.parse).makeTwoWay(go.Point.stringify),
new go.Binding("desiredSize","desiredSize",go.Size.parse).makeTwoWay(go.Size.stringify),
g_(go.Shape, "Rectangle",
{ fill: null, stroke: "#ff0000", strokeWidth: 3 ,minSize: new go.Size(100, 100)}),
g_(go.TextBlock,
{
alignment: go.Spot.Center,
//margin: new go.Margin(0, 14, 0, 2),
font: "bold 16px sans-serif"
},
new go.Binding("alignment").makeTwoWay(),
new go.Binding("font","font"),
new go.Binding("stroke","color"),
new go.Binding("text","text").makeTwoWay()
)
);
