Hi, list!
I’m trying to make a WFS insert transaction with OpenLayers to a GS 2.1.2 PostGIS layer.
My request is:
<wfs:Transaction xmlns:wfs=“http://www.opengis.net/wfs” service=“WFS” version=“1.0.0” xsi:schemaLocation=“http://www.opengis.net/wfs http://schemas.opengis.net/wfs/1.0.0/WFS-transaction.xsd” xmlns:xsi=“http://www.w3.org/2001/XMLSchema-instance”>
wfs:Insert
<feature:plots xmlns:feature=“landws”>
feature:the_geom
<gml:MultiPolygon xmlns:gml=“http://www.opengis.net/gml” srsName=“EPSG:900913”>
gml:polygonMember
gml:Polygon
gml:outerBoundaryIs
gml:LinearRing
<gml:coordinates decimal=“.” cs=“,” ts=" ">4112493.6591121,7609090.535939 4111461.7592304,7607867.5434866 4114041.5089347,7606701.8788054 4114098.8367059,7609472.7210804 4112493.6591121,7609090.535939</gml:coordinates>

</gml:Polygon>
</gml:polygonMember>
</gml:MultiPolygon>
</feature:the_geom>
</feature:plots>
</wfs:Insert>
</wfs:Transaction>
I get a wfs:FAILED/ status in the response.
The log says:

The request is generated by OpenLayers, so I guess that coordinates are right.
Can anyone please help? I’m stuck with investigating on it.
I have a similar problem.
My geometry is of type Linestring and the SRS is epsg:4326
PostgreSQL-8.4.8, PostGIS-1.5.2
I'm including the DEBUG messages

Nikolay,
I found the cause of my problem.
The DrawFeature control is creating MultiLinestring geometries while the layer needs a LineString. Setting the geometryType if the vector layer didn’t work. So I implemented a small function for the onFeatureInsert event in the layer definition to make it LineString.
// geometryType: “OpenLayers.Geometry.LineString”,
onFeatureInsert: function(feature){
feature.geometry = feature.geometry.components[0];
},
I should probably do some type checking before I assign the first geometry, but this is working for now.

Hola Nick :
/Hi Nick : /
El mensaje de error que te bota el firebug *"Error performing insert:
java.lang.String cannot be cast to com.vividsolutions.jts.geom.Geometry"* se
debe a que el geoserver o las funciones del geoserver para el servicio wfs
solo reconoce a los tipo de datos (TYPE) *POLYGON*, *LINESTRING *y *POINT*
de la tabla geometry_columns. Si deseas poder dibujar todo tipo de
geometría, deberás crear una capa *"OpenLayers.Layer.Vector"* para cada tipo
de geometría.
/The error message you boot the firebug * "Error performing insert:
java.lang.String can not be cast to com.vividsolutions.jts.geom.Geometry" *
is that the geoserver or functions of geoserver wFS service for only
recognizes the data type (TYPE) * POLYGON *, * LINESTRING * and * POINT *
GEOMETRY_COLUMNS table. If you want to draw all kinds of geometry, you must
create a layer * "OpenLayers.Layer.Vector" * for each type of geometry./
Saludos.
/Regards./

Hi Chaitanya,
I would like to have some more information about your solution, in the case
of a message error occuring because of an inappropriate geometryType.
You wrote :
chaitanya_ch wrote
// geometryType: "OpenLayers.Geometry.LineString",
onFeatureInsert: function(feature){
feature.geometry = feature.geometry.components[0];
},
How do you insert it ?
Something like this ?
var wfs = new OpenLayers.Layer.Vector("wfs", {
strategies: [new OpenLayers.Strategy.Fixed(), saveStrategy],
protocol: new OpenLayers.Protocol.WFS({
url: ".../geoserver/wfs",
featureType: "wfs",
featurePrefix: "1",
geometryName: "the_geom"
}),
styleMap: selectionStyleWFS,
rendererOptions: {zIndexing: true},
renderers: renderer,
projection: "EPSG:2100",
geometryType: "OpenLayers.Geometry.LineString",
onFeatureInsert: function(feature){
feature.geometry = feature.geometry.components[0];
},
}
Because it's not working for me. Thank you for your help.

Hi, I also encountered the same problem,but my postgre geometryType is
multilinestring, openlayers post a lineString to geoserser,So, I set the
"multi" value of DrawFeature Control as follow:
new OpenLayers.Control.DrawFeature(layer, OpenLayers.Handler.Path, {
displayClass: 'olControlDrawFeaturePath',
handlerOptions: {citeCompliant:
this.citeCompliant,multi:true}
});
My problem is solved；
Can find the way to set automatically the value by the schema?
