Re: [mapserver-users] WFS gml:null

[Milo van der Linden]

Thank you Bart for the response.

I tried BBOX'n my request.

I tried both:
-  SRS=epsg:4326&bbox=-180,-90,-180,-90
and
- -  SRS=epsg:28992&bbox=0,300000,300000,600000

But none of that did the trick..

What happens if you add a BBOX filter to your request? You probably need to
specify the coordinates in the SRS of your LAYER.

The BBOX filter defaults to the Map's Extent which could be why it's
returning 0 features since of the projection difference.

Best regards,
Bart

Hello list!

I have been surfing the list all morning looking for a solution on why my mapserver is returning a gml:null.

Couldn't find any documentation.

The problem:

I do a WFS request on a mapfile that contains a esri shapefile. The layer I request has a different SRS than the main map.

http://www.myserver.org/cgi-bin/mapserv.exe?map=awfsenabled.map&SERVICE=WFS&VERSION=1.0.0&REQUEST=getFeature&TYPENAME=percelen

it returns

<?xml version='1.0' encoding="ISO-8859-1" ?>
<wfs:FeatureCollection
   xmlns:ms="http://mapserver.gis.umn.edu/mapserver"
   xmlns:wfs="http://www.opengis.net/wfs"
   xmlns:gml="http://www.opengis.net/gml"
   xmlns:ogc="http://www.opengis.net/ogc"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   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://www.myserver.org/cgi-bin/mapserv.exe?map=awfsenabled.map&SERVICE=WFS&VERSION=1.0.0&REQUEST=DescribeFeatureType&TYPENAME=percelen&OUTPUTFORMAT=XMLSCHEMA">

   <gml:boundedBy>
      <gml:null>missing</gml:null>
   </gml:boundedBy>
</wfs:FeatureCollection>



Here is my layer definition.

The problem is whatever I do, whether I set wfs_extent or not, it keeps returning gml:null
