Hi,
I'm trying to output the content of a Multipolygon PostGis Table using WFS
Server feature of mapserver.
I created a simple map using some tutorial on the web. the data are in a
postgis DB with MULTIPOLYGON geometry, and srid filled.

-------- start ---------
EXTENT -2200000 -712631 3072800 3840000
UNITS METERS
IMAGECOLOR 255 255 255

WEB
  IMAGEPATH "/ms4w/tmp/ms_tmp/"
  IMAGEURL "/ms_tmp/"
  METADATA
    "wfs_title"            "Wfs TEST (FROM FRANCE.GMF)"  ## REQUIRED
    "wfs_onlineresource"   "http://127.0.0.1/cgi-bin/mapserv.exe?"  ##
Recommended
    "ows_schemas_location" "http://ogc.dmsolutions.ca"  ## Optional
  END
END

PROJECTION
  "init=epsg:27582"
END

LAYER
  NAME departement
  CONNECTIONTYPE postgis
  CONNECTION "user=postgres dbname=postgis host=localhost password=xxxxx"
  METADATA
    "wfs_title"    "departement" ## REQUIRED
    "gml_featureid" "gid" ## REQUIRED
    "gml_include_items" "all"  ## Optional (serves all attributes for layer)
  END
  TYPE POLYGON
  STATUS ON
  DATA "geom_column FROM departement AS foo USING UNIQUE gid AND USING
srid=27582"
  DUMP TRUE           ## REQUIRED
END # Layer
END # Map File
-------- end ----------

I access to it using "
http://localhost/mapserv?SERVICE=WFS&VERSION=1.0.0&REQUEST=GETFEATURE&TYPENAME=departement
"
(I used httpd.conf to indicate the .map file)

And the server answer me an empty feature collection:

------- start ----------
<wfs:FeatureCollection xsi:schemaLocation="http://www.opengis.net/wfs
http://ogc.dmsolutions.ca/wfs/1.0.0/WFS-basic.xsd
http://mapserver.gis.umn.edu/mapserver
http://127.0.0.1/cgi-bin/mapserv.exe?SERVICE=WFS&VERSION=1.0.0&REQUEST=DescribeFeatureType&TYPENAME=departement&OUTPUTFORMAT=XMLSCHEMA
">
    <gml:boundedBy>
    <gml:Box srsName="EPSG:27582">
    <gml:coordinates>
47680.000000,1620480.000000 1197822.000000,2677441.000000
</gml:coordinates>
</gml:Box>
</gml:boundedBy>
</wfs:FeatureCollection>
--------- end ---------

I don't understand why, my postgis DB is well filled, it works with
GeoServer but not with mapserver and my map file. I think my map file is
erronous but don't know where :s
Can i have some help please ;p

I'm using latest Stable Release of mapserver and postgis

Feel free to ask for more details

Thanks a lot!
