[Mapserver-users] WFS layers

[Bart van den Eijnden]

Hi,

I have just been able to reproduce your problem. It is caused when you (or 
Mapserver) request(s) data in a BBOX where there is no data found. But 
this is not the way a WFS should respond, so I have filed a bug for it, 
see:

http://mapserver.gis.umn.edu/bugs/show_bug.cgi?id=597

Best regards,
Bart
