Hi, I've implemented this, and started testing. To test if it was working I did two things:
I looped through all the graphics in featureSet.features and created a new MapPoint from the geometry property of each graphic, then used the Alert to display the x and y values of the MapPoint. Always, this showed "0 0".
Then I created another graphics layer and tried to set the featureSet.features to the graphicProvider of the layer. No geometry is displayed.
The reason I need the featureSet is because I need to use it as an input parameter for a network analyst model.
Thanks
