OrthogonalLayout.Arrange error

A number of errors are thrown, play source code follows.

I'm developing a simple tool to import schema definitions from a CRM product and display tables with foreign key links which don't use foreign key rel but some other meta data.

Sample input is three tables.

I can get one of the following:

No nodes in diagram:

Sample code.  I've tried simplifying as much as possible but it makes no difference.

Code
Select All
	  private void btnDiagram_Click(object sender, EventArgs e)
	  {
		foreach (CheckedListBoxItem i in lbTables.CheckedItems)
		{
		    Table table = i.Value as Table;
		    if (!_AddedTableNodes.ContainsKey(table.Name))
		    {
			  TableNode tn = new TableNode(diagram1);
			  table.TableNode = tn;
			  tn.OffsetHeaderRows = true;
			  tn.Tag = table;
			  tn.RedimTable(2, 1);
			  tn[0, 0].Text = table.PrimaryField.FieldName;
			  tn[1, 0].Text = "Key";
			  tn.Caption = "<b>" + table.Name + "</b>";
			  tn.EnableStyledText = true;

			  diagram1.Nodes.Add(tn);

			  _AddedTableNodes.Add(table.Name, tn);
		    }
		}

		foreach ( TableNode tableNode in _AddedTableNodes.Values)
		{
		    foreach ( TableField field in ((Table) tableNode.Tag).Fields.Values)
		    {
			  Table foreignTable = field.ForeignTable;
			  if (foreignTable != null && _AddedTableNodes.ContainsKey(foreignTable.Name ))
			  {
				int row = tableNode.AddRow();

				tableNode[0, row].Text = field.FieldName;
				tableNode[1, row].Text = "F";
				DiagramLink dl = new DiagramLink(diagram1, tableNode, foreignTable.TableNode);
				dl.AutoRoute = true;
				diagram1.Links.Add(dl);



			  }
		    }

		    tableNode.ResizeToFitText(false);

		    float newHeight = tableNode.CaptionHeight +
			  Constants.GetPixel(diagram1.MeasureUnit) +
			  3 * tableNode.Pen.Width;
		    foreach (TableNode.Row row in tableNode.Rows)
			  newHeight += row.Height;

		    tableNode.Resize(tableNode.Bounds.Width, newHeight);



		}

		OrthogonalLayout layout =new OrthogonalLayout();
		layout.Anchoring = Anchoring.Reassign;
		layout.Refine = true;
		layout.Arrange(diagram1);
		diagram1.ResizeToFitItems(5);



	  }
