[mapserver-users] WFS gml:null

[Bart van den Eijnden (OSGIS)]

What happens if you add a BBOX filter to your request? You probably need to
specify the coordinates in the SRS of your LAYER.

The BBOX filter defaults to the Map's Extent which could be why it's
returning 0 features since of the projection difference.

Best regards,
Bart
