Map.WrapAround and FeatureLayer.Geometry not returning results

ChrisSmith — Tue, 04 Oct 2011 08:54:14 GMT

Hi

I have set the Map.WrapAround property to true, the user can draw a polygon and the result of this is set as the FeatureLayer.Geometry property, FeatureLayer.Update() is then called. This returns the correct results.

If the user then pans the original world frame a couple of times to the left or right passing the dateline and the process as above is completed the FeaturLayer returns no results.

I have tried using the Geometry.NormalizeCentralMeridian() as suggested in the whats new section..

Am I missing something obvious?

Thanks

Chris

Ok it works with a simple polygon, but if the geometry is a circle or a freehand line that has been closed to make a polygon it produces no results once the map has panned beyond the dateline.

have worked out what the issue is, the Normalize method expects the geometry to have a spatialreference set.
