Getting popup coordinates in popup window

[KenDoman]

I'm trying to configure a popup on a polygon to add a link to another site. The other site's url requires latitude and longitude in the query parameters to show the data in that location. How can I display the popup's latitude or longitude in the popup window, if those coordinates are not fields in the data?

Were you able to find a way to get the coordinates inside in the PopUp for Flex?
If you did, please let me know.
