[Geomoose-users] debugging mapserver WFS layer search

[karsten]

Hi All,
 
I have configured my first Geomoose v 3 pilot project and got all working
except a MapServer WFS layer search on a PostGIS layer. I am using ms4w v
3.2.3  and the app package geomoose 3.1. I have successfully added a
firestation WFS search to the desktop demo
<http://localhost/gm3/desktop/index.html>
http://localhost/gm3/desktop/index.html following  the instructions at
<http://geomoose.github.io/gm3/howto/add-search.html>
http://geomoose.github.io/gm3/howto/add-search.html .
Now I have used MapServer WMS for many years but this is the first time I am
using WFS; so am a bit lost of how to debug my own custom layers search in
Geomoose.
In a copy of the desktop app I added my own data and so on but the search on
one parcel layer I have added (a MapServer WFS layer drawn from PostGIS)
returns no errors but empty gml results. 
 
The request I can see is 
http://localhost/cgi-bin/mapserv.exe?MAP=c:/data/mapfiles/mechernich.map
<http://localhost/cgi-bin/mapserv.exe?MAP=c:/data/mapfiles/mechernich.map&ty
pename=ms:flurstueck_wfs> &typename=ms:flurstueck_wfs
plus the post params
MAP	 c:/data/mapfiles/mechernich.map	
typename    	 ms:flurstueck_wfs	
 
<GetFeature xmlns=" <http://www.opengis.net/wfs> http://www.opengis.net/wfs"

wildCard="*" singleChar="." escapeChar="!"
matchCase="false"><PropertyName>lagebezeichnung</PropertyName><Literal>*Auf*
</Literal></PropertyIsLike></Filter></Query></GetFeature>
 
 
The response gives me an empty bounding box and feature collection (when
there are many objects that should be found using the string "Auf" - tried
it with a postgres SQL query that gave me > 2200 results):

</wfs:FeatureCollection>

 
I have tried to include all that is needed in the mapsertver layers see
below (even changed the data tag to a sub select to make sure all atributes
are retrieved for sure ...
 
 
Would anyone have suggestions how to debug this ?
 
Cheers
