I think there is a bug. When I use toScreenX and toScreenY in my custom MarkerSymbol I always get the marker position on the screen when the map is in default extent. (the center of the map)
I use this to show a InfoWindow on top of my Marker, when I click the marker. (Like google maps, this functionality is missing here in ArcGIS Flex).
When I pan the map, the InfoWindow opens on the "old marker start position on the screen" and not over the new marker position.
If source code is required, I can attach source code.
Marcus,
It is hard to determine if you are using the function properly in your code based on your description. You should post your code.
I have no idea how to attach files to this issue. So I uploaded 2 files to "Documents".
Thank you for your quick response!
And here is the swf
Marcus,
I am having some issue with getting the correct wraparound screen coordinates as well, so I have a question into the Flex Dev team lead right now and I will let you know the status.
