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?

Hi Robert,

Can you attach a reproducible app to see the issue?

Thanks,

Asser

[RobertKennedy]

Hi Asser,

Sure thing, I was hoping to see if I'd get any quick responses before needing to pull it out of our product and into a stand alone app, but I can certainly look into that.  I'll keep you posted.

Cheers,

Bobby

Hi Bobby,

We have fixed a couple of issues recently which might give rise to this exception - which is why we are keen to test your scenario on the latest internal build.

Are you sharing one layer instance between multiple active MapViews?

Cheers

Mike
