The Swim Lanes sample has each lane/Group with its own layout because it assumes that there are few links that cross lanes. Just as in a real swimming pool, where one does not normally cross over lanes.
Could please tell me, if i can sort the swimlane order programmatically. So that, all the lane appear in a fixed order every time, assuming that i have introduced a node property for swimlanes, say, index, using which i want to sort the order for swimlane visualization.
