MGRS in Web Mercator

[BridgetHayes]

We recently changed from WGS84 to Web Mercator.  I've noticed the USNG widget is no longer displaying coordinates.  Has anyone changed this code to fit this situation?

Thanks

I'm not using it in the Flex Viewer, but this is the projection information that's in my code for a Web Mercator service.

private var layerGraticule:SimpleGraticuleLayer = new SimpleGraticuleLayer;
layerGraticule.projection = new Mercator(new Ellipsoid(6378137,0,""),0,0,0,0, LinearUnit.METER);
