Dear *
I'm stuck for some time experiencing a strange behavoiur with WFS POST requests to stored querys on our mapserver (v.8.0.1/ubuntu 22.04) and can't seem to find anythin helpful in the logs or on the web. The server is public, so you can see for yourselves. To describe the issue I'll stick to our address service providing the addresses in Freiburg im Breisgau, Southwest Germany. https://geoportal.freiburg.de/wfs/gdm_address/gdm_address?SERVICE=WFS&VERSION=2.0.0&REQUEST=GetCapabilities The service is supposed to answer both GET and POST requests. This does work just fine for "normal" GetFeature requests. However, there seems to be an issue with stored queries. E.g. we set up some stored query for searching addresses taking a street name and a house number as an argument. It can be easily queried by calling e.g. https://geoportal.freiburg.de/wfs/gdm_address/gdm_address?SERVICE=WFS&version=2.0.0&REQUEST=GetFeature&StoredQuery_ID=findeStrasseHnr&strassenname=fehren&hausnummer=12 wheras "strassenname" is the street name and "hausnummer" the house number. The GET call will return one matching feature as expected. The same request as POST to https://geoportal.freiburg.de/wfs/gdm_address/gdm_address <GetFeature xmlns="http://www.opengis.net/wfs"; service="WFS" version="2.0.0" maxFeatures="3" xsi:schemaLocation="http://www.opengis.net/wfs http://schemas.opengis.net/wfs/1.1.0/wfs.xsd"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";> <StoredQuery id="findeStrasseHnr" xmlns="http://www.opengis.net/wfs"; typeName="ms:addresses" srsName="urn:ogc:def:crs:EPSG::25832" xmlns:ms="http://mapserver.gis.umn.edu/mapserver";> <Parameter name="strassenname">fehren</Parameter> <Parameter name="hausnummer">12</Parameter> </StoredQuery> </GetFeature> however will only return <?xml version='1.0' encoding="UTF-8" ?> <wfs:FeatureCollection xmlns:ms="http://mapserver.gis.umn.edu/mapserver"; xmlns:gml="http://www.opengis.net/gml/3.2"; xmlns:wfs="http://www.opengis.net/wfs/2.0"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="http://mapserver.gis.umn.edu/mapserver https://geoportal.freiburg.de/wfs/gdm_address/gdm_address?SERVICE=WFS&VERSION=2.0.0&REQUEST=DescribeFeatureType&TYPENAME=ms:addresses&OUTPUTFORMAT=application%2Fgml%2Bxml%3B%20version%3D3.2 http://www.opengis.net/wfs/2.0 http://schemas.opengis.net/wfs/2.0/wfs.xsd http://www.opengis.net/gml/3.2 http://schemas.opengis.net/gml/3.2.1/gml.xsd"; timeStamp="2023-10-05T16:10:00" numberMatched="unknown" numberReturned="0"> </wfs:FeatureCollection> Strange enough, it will also log some weired error at DEBUG 5: [Fri Oct 6 14:59:29 2023].546904 msWFSParseRequest(): WFS post request: <GetFeature xmlns:wfs="http://www.opengis.net/wfs"; service="WFS" version="2.0.0" maxFeatures="200" xsi:schemaLocation="http://www.opengis.net/wfs http://schemas.opengis.net/wfs/1.1.0/wfs.xsdhttp://www.opengis.net/wfs%20http:/schemas.opengis.net/wfs/1.1.0/wfs.xsd"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";><StoredQuery id="findeStrasseHnr" xmlns="http://www.opengis.net/wfs"; typeName="ms:addresses" srsName="EPSG::25832"><Parameter name="strassenname">fehren</Parameter><Parameter name="hausnummer">12</Parameter></StoredQuery></GetFeature> [Fri Oct 6 14:59:29 2023].622878 FLTLayerApplyPlainFilterToLayer(): (("[strassenname]" ~* "^.*feh.*$") AND (([hausnummer] =* 12) AND ("[hausnummernzusatz]" = ""))), rect=399550,5305350,420740,5325690 [Fri Oct 6 14:59:29 2023].689509 msPostGISLayerTranslateFilter(): General error message.
