[mapserver-users] wfs problem <gml:null>missing</gml:null>

[dstroeer at uni-osnabrueck.de]

Hello,

I'm testing a WFS-Layer in OpenLayers.  So first of all I set up a WFS in
epsg:4326. You can see the mapfile below...
Now I want to put his WFS into a OpenLayers project. Here we've got a
simple OpenStreetMap WMS, also in epsg:4326. But when I'm testing my
OpenLayers application (code below), I don't see my WFS layer.

So I'm using firebug and I can see that OpenLayers tries the following
request:

http://localhost/cgi-bin/mapserv.exe?map=C:/ms4w/Apache/htdocs/mapserverII/wms_wfs/wfs_ogc/wfs_server_4326.map&TYPENAME=Testdatenlayer&SERVICE=WFS&VERSION=1.0.0&REQUEST=GetFeature&SRS=EPSG%3A4326&BBOX=3.60546875,50.802734375,12.39453125,55.197265625

When I try this request in Firefox, I'm getting the following result:

<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://localhost/cgi-bin/mapserv.exe?map=C:/ms4w/Apache/htdocs/mapserverII/wms_wfs/wfs_ogc/wfs_server_4326.map&SERVICE=WFS&VERSION=1.0.0&REQUEST=DescribeFeatureType&TYPENAME=Testdatenlayer&OUTPUTFORMAT=XMLSCHEMA"><gml:boundedBy><gml:null>missing</gml:null></gml:boundedBy></wfs:FeatureCollection>


When I'm cutting the BBOX parameter like this

http://localhost/cgi-bin/mapserv.exe?map=C:/ms4w/Apache/htdocs/mapserverII/wms_wfs/wfs_ogc/wfs_server_4326.map&TYPENAME=Testdatenlayer&SERVICE=WFS&VERSION=1.0.0&REQUEST=GetFeature&SRS=EPSG%3A4326

I can see a list of my features:
...
<gml:boundedBy><gml:Box
srsName="EPSG:4326"><gml:coordinates>3449790.000000,5891640.000000
3470274.000000,5940811.000000</gml:coordinates></gml:Box></gml:boundedBy><gml:featureMember><ms:Testdatenlayer
fid="Testdatenlayer.1"><gml:boundedBy><gml:Box
srsName="EPSG:4326"><gml:coordinates>3463543.000000,5900876.000000
3463543.000000,5900876.00000
...

It seems to be a projection problem, but I don't know where...
So now I want to ask if there are any problems with my mapfile or if I
made another mistake?

Thanking you in anticipation,

D. Stroeer
