System.Exception: Invalid argument : Invalid graphic ID!

RobertKennedy

Hi All,

I'm curious is anyone has seen this exception before and had any ideas on resolution.

Background:

Basically we periodically create and remove graphics in a GraphicsOverlay, something akin to the following:

Add:

MapPoint pt = new MapPoint(lon, lat, elev, SpatialReferences.Wgs84);

pt = GeometryEngine.Project(pt, myMapRefSsytem) as MapPoint;

Graphic g = new PictureMarkerSymbol();

g.SetSourceAsync(new Uri(iconAnno.IconPath));

myGraphicsOverlay.Graphics.Add(g);

Remove:

myGraphicsOverlay.Graphics.Remove(f.Gfx);

Apparently submitted early.

Anyway, that typically works fine, but occasionally the arcgis API throws the exception listed below.

Anyone have any ideas?
