[TinyOWS-dev] Error when inserting new feature with TinyOWS

[Rahkonen Jukka]

Hi,

You can't have success with WFS 1.1.0 because your geometry is in GML2
<gml:coordinates
However, you had some other problem too with the schema location. I can't say anything about that. Anyway, be sure to use GML2 with WFS 1.0.0 and GML3 with WFS 1.1.0.

I have other layers in the map viewer too, configured with OpenLayers, but the layer that I configured with TinyOWS is supposed to be editable. Anyway, I can edit and delete features from the layer. But unfortunately I haven't managed yet to insert new features.

In the log of TinyOWS, when I try to insert a new feature, I keep getting an error:

[ERROR] Element '{http://www.tinyows.org/}olives': This element is not expected. Expected is one of ( {http://www.opengis.net/gml}_Feature, {http://www.opengis.net/wfs}FeatureCollection )

Just before the error, in the log file I see this query:
<wfs:Transaction xmlns:wfs="http://www.opengis.net/wfs" service="WFS" version="1.1.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.opengis.net/wfs http://schemas.opengis.net/wfs/1.1.0/WFS-transaction.xsd">

        </gml:MultiPolygon>
      </feature:geometry>
    </feature:olives>
  </wfs:Insert>
</wfs:Transaction>


The config.xml is like this:
<tinyows online_resource="http://localhost:81/cgi-bin/tinyows.exe"
  schema_dir="C:/ms4w/apps/tinyows/schema/"
         log="C:/ms4w/apps/tinyows/tinyows.log"
         log_level="15">
  <pg host="127.0.0.1" user="postgres" password="***" dbname="olives_gis1" port="5432"/>
  <metadata name="Olives WFST Server"
         title="WFST Olives" />

  <layer retrievable="1"
         writable="1"
         ns_prefix="tows"
         ns_uri="http://www.tinyows.org/"
         //srid="EPSG:32634"
         name="olives"
         title="olives"/>
</tinyows>

I thought the error might happen because in the database the geometry of the table olives is declared as POLYGON, so I changed it to MULTIPOLYGON, but I still got the same error. I also changed the WFS schema to 1.0.0, but still the same error.

I have declared a DrawFeature variable like this, to draw the feature that will be saved in the database:

    var draw = new OpenLayers.Control.DrawFeature(
      wfs, OpenLayers.Handler.Polygon,
      {
          title: "Add olives",
          displayClass: "olControlDrawFeaturePolygon",
          multi: "true",
          id: "draw"
      }
  );


I would like to mention again that the editing and deleting of existing features work very well.

I am using MS4W 3.0.4 (with OL included) and tinyows-1.0.0rc3. The database is in PostgreSQL & PostGIS.

Since I don't have much experience with these technologies (more than 1 month) I might have made some stupid error, but I cannot find it anyway...

Thanks a lot in advance for your help
