Hi, Your spatial filter is not WFS 1.1.0 filter because 1.1.0 is using gml3."coordinates" belong to gml2. Have a try with WFS 1.0.0.

I use PostgreSQL/PostGIS (8.4.4/1.5.1) as datastore in this case. The spatial reference system is EPSG:25832 und the type of the geometry is MULTIPOLYGON. OS is Suse Linux Enterprise Server 11, Servicepack1. WMS and WFS work fine until I use a spatial filter within the getFeature-Request of the WFS. In this case the response doesn't deliver any features. Nevertheless the number of features (e.g. numberOf Features='4') is correct. I tried this out with a couple of different boundingboxes and the known number of features that intersect these boundigboxes. In all cases I do not get any features back, but always the right number. So it seems that at least the intersection of the boundingbox and my data works correctly. Please take a look at the following request and response that illustrate that problem: Request: http://myserver/cgi-bin/mapserv?map=/mapserver/mapfiles/u218768/ku_testwfs.map&REQUEST=getFeature&typename=folie001&SERVICE=WFS&VERSION=1.1.0&; Filter=<ogc:Filter> <Intersects> <ogc:PropertyName>msGeometry</ogc:PropertyName> <gml:Polygon srsName='EPSG:25832'> <gml:outerBoundaryIs> <gml:LinearRing> <gml:coordinates>409350,5709890 409350,5709910 409370,5709910 409370,5709890 409350,5709890</gml:coordinates> </gml:LinearRing> </gml:outerBoundaryIs> </gml:Polygon> </Intersects> </ogc:Filter> Response <?xml version="1.0" encoding="ISO-8859-1" ?> <wfs:FeatureCollection xmlns:ms="http://mapserver.gis.umn.edu/mapserver"; xmlns:gml="http://www.opengis.net/gml"; xmlns:wfs=http://www.opengis.net/wfs xmlns:ogc="http://www.opengis.net/ogc"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="http://mapserver.gis.umn.edu/mapserver http://myserver/cgi-bin/mapserv?map=/mapserver/mapfiles/u218768/ku_testwfs.map&SERVICE=WFS&VERSION=1.1.0&REQUEST=DescribeFeatureType&TYPENAME=folie001&OUTPUTFORMAT=text/xml; subtype=gml/3.1.1 http://www.opengis.net/wfs http://schemas.opengis.net/wfs/1.1.0/wfs.xsd"; numberOfFeatures="4"> <gml:boundedBy> <gml:Envelope srsName="EPSG:25832"> <gml:lowerCorner>-1.000000 -1.000000</gml:lowerCorner> <gml:upperCorner>-1.000000 -1.000000</gml:upperCorner> </gml:Envelope> </gml:boundedBy> </wfs:FeatureCollection> Indeed of this behavior the WFS returns features when I do not use a spatial filter. Therefore in my opinion the WFS should be configured right in general. To me the spatial filter seems to be the problem. Unfortunately I do not have any ideas what is going wrong. For more information you can take a look at my MapFile and a part of the capabilities document returned from the WFS below: MAP NAME "ku_testwfs" STATUS ON SIZE 400 520 EXTENT 389965 5693582 420177 5732815 UNITS METERS PROJECTION "init=epsg:25832" END SYMBOLSET "/mapserver/symbols/symbols_alk.sym" FONTSET "/mapserver/fonts/fonts.fnt" IMAGECOLOR 255 255 255 WEB IMAGEPATH "/mapbender/mb262/http/tmp/" IMAGEURL "http://myserver/mapbender/tmp/"; METADATA "ows_onlineresource" "http://myserver/cgi-bin/mapserv?map=/mapserver/mapfiles/u218768/ku_testwfs.map"; "ows_title" "Liegenschaftskarte, Kreis Unna" "ows_accessconstraints" "Nutzung nur für den Dienstgebrauch."

This seems to be strange since thes doesn' t occur in the WMS-capabilities document. In this document the LatLongBoundingBox und the BoundingBox in the source SRS are both all right.) I even tried different versions of MapServer and I discovered a slight difference with other versions. If I change my datasource from PostGIS to OGR/MapInfo Tab former versions of MapServer (5.4.2/5.2.3) provide features as well. But just in case of OGR/MapInfo Tab - not with PostGIS in use! As I have to use PostGIS I'm interested in any hints to solve this problem. Therefore I would be glad to hear from you! Thanks so far and best regards!
