Location.Empty with LineData

[Jason D]

I have a visualization layer bound to an observable collection of MapShapeData. There is a LineData in it whose initial points are Location.Empty. As I change Point1 and Point2, the line is correctly updated on the map. When I change Point1 and Point2 back to Location.Empty, the line stays on the map. I am expecting it to disappear.

This was the only simliar thread I saw:

Actually, using a PolyLineData and clearing the Points collection also does not make the shape disappear.

Hello Jason,

The issue you described is known to us and has been logged in our feedback portal. You can subscribe to the bug report to get notified about any changes in its status.

As stated there, currently, the only workaround we can offer is to remove the data directly from the visualization layer.

this.layer.Items.Remove(polylineData);

I do hope you find such an approach applicable for the time being.
