Attached nodes are not appearing in proper position when swimlanelayout is enabled.

MasterNode.MasterGroup.MainItem.LayoutTraits.Add(MindFusion.Layout.SwimlaneLayou
tTraits.Lane, index);
foreach (DiagramNode attachednode in MasterNode.MasterGroup.AttachedNodes)
attachednode.LayoutTraits[MindFusion.Layout.SwimlaneLayoutTraits.Lane] = index;


int index = grid.RowHeaders.Add(new MindFusion.Diagramming.Wpf.Lanes.Header());
grid.RowHeaders[index].Width = 30;
grid.RowHeaders[index].Height = 60;
grid.RowHeaders[index].RotateTitle = true;

foreach (Swimlane swimlane in process.Swimlanes)
{
index = grid.RowHeaders.Add(new MindFusion.Diagramming.Wpf.Lanes.Header(swimlane.Name));
grid.RowHeaders[index].Width = 30;
grid.RowHeaders[index].Height = 60;
grid.RowHeaders[index].RotateTitle = true;
}

designerCanvas.EnableLanes = true;

SwimlaneLayout layout = new SwimlaneLayout();
layout.NodeDistance = 50;
layout.LaneDistance = 30;
layout.Arrange(designerCanvas);

Why?

Wow Excellent. Worked. Thanks Stoyan.
