[Luca Delucchi]

I everebody, this is my first post. I'm an italian GFOSS user, I
developed several service using mapserver before this, but never I had
this error and I cannot found a solution.
I developed a WFS service, the GetCapabilities work well but when I
try the GetFeatures it return an error

<wfs:FeatureCollection xsi:schemaLocation="http://www.opengis.net/wfs
http://schemas.opengis.net/wfs/1.0.0/WFS-basic.xsd
    http://mapserver.gis.umn.edu/mapserver
http://acesap.fem-environment.eu/mapserv/wfs_acesap?SERVICE=WFS&VERSION=1.0.0&REQUEST=DescribeFeatureType&TYPENAME=ACESAP_field_data&OUTPUTFORMAT=XMLSCHEMA">
-
<gml:boundedBy>
<gml:null>missing</gml:null>
</gml:boundedBy>
</wfs:FeatureCollection>

someone can help me?

I am attaching the mapfile if necessary, but I checked several times
and showed others Italians and looks good

thanks
Luca
