Can't connect ports

GoJS
1

Hi
i am connecting two tables.But I am not ABLE TO CONNECTING TWO COLUMNS.i don’t think what’s the problem port is not working properly or any other problem.
template is like this:
name: “SCROLLING”,
desiredSize: new go.Size(150, 150),
“TABLE.itemTemplate”:
goJs(go.Panel, “TableRow”,
{
defaultStretch: go.GraphObject.Horizontal,
fromSpot: go.Spot.LeftRightSides, toSpot: go.Spot.LeftRightSides,
toLinkable: true, fromLinkable: true,
},
new go.Binding(“portId”, “LOGICALCOLUMNNAME”),
goJs(“CheckBox”, “checked”, { column: 0,width:15 },
{ “_doClick”: function (e, obj) { Ciel.Process.ProcessDesign.JoinStep.UpdatedColumnInTable(e, obj); } },
new go.Binding(“checked”, “checked”).makeTwoWay()),
goJs(go.TextBlock, { column: 1 }, new go.Binding(“text”, “LOGICALCOLUMNNAME”))
I am using scrolling table concept

Users can draw new links in this sample: Scrolling Table

However, I do notice that scrolling is not updating the link routes any more. We’ll fix that for the next release.

You have not provided any information so that we can guess what is wrong in your app. I suggest that you read GoJS Ports in Nodes-- Northwoods Software and GoJS Validation -- Northwoods Software carefully to see if perhaps you forgot something.
