This class extends your MVCArrayBinder. I agree that the aim of this exercise is to make something reusable. Here it is used to implement the polyline editor. Clicking on the map adds a new vertex at the end of the polyline. Vertices are moved by dragging the markers. Clicking a marker inserts a vertex at the midpoint of the following segment. Right clicking a marker deletes a vertex. Clicking the final marker toggles the drawing mode, so a new vertex gets added before the start of the polyline.
