Possible GroupLayer Bug

[DavidCulverhouse]

GroupLayer does not render GraphicsLayers that are added to the GroupLayer.ChildLayers after the GroupLayer is already added to the map.

Workaround: Call GroupLayer.Initialize after GraphicsLayer is added to GroupLayer.ChildLayers

Attached is a simple example with this behavior.

I think you might be correct, as I am seeing the same behavior.

PS: Thanks for the idea of calling <parentgroup>.Initalize(), that worked for me!

Yes. We are aware of the issue and we'll try to get it fixed in a future version.

Thansk for reporting that.
