Adding XY when creating a new feature with Edit Widget

Hi,

I am a little new to Flex and trying to flesh everything out. I have implemented the Edit widget on my viewer and was wondering if there was a way to populate and X and Y fields automatically when the feature is created. When I create a new feature in the viewer I can manually add the details but I noticed in ArcMap that there is location info when I identify the point. Is there a way I can add the XY data to the attribute table?

Edit: Also, is there a way to do the same with the a timestamp field? i.e. populate a timestamp field with the time the feature was created?

Thanks,
Spencer
