[OpenLayers-Users] Displaying lat long coordinates for projected map?

[Eric Lemoine]

Hello. Have you tried setting displayProjection in the map options as
opposed to in the mouse position control options? I cant check right
now but i dont remember having seen this option in the mouse position
control. Regards. Eric
