Hi again, Thank you Alexandre. Yes It helped me. I was just being dumb I think. The namespace got detected by OL since the prefix was the same in the server response.
So now I can modify and delete features. But I cannot insert new features to the postgis database. This is the GML insert openlayers is sending to the tinyOWS server: <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 http://**.***.**.*** http://**.***.**.*** /cgi-bin/tinyows?service=WFS&version=1.0.0&request=DescribeFeatureType&TypeName=world2" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";> <wfs:Insert> <feature:world2 xmlns:feature="http://**.***.**.*** "> <feature:the_geom> <gml:MultiPolygon xmlns:gml="http://www.opengis.net/gml"; srsName="EPSG:4326"> <gml:polygonMember> <gml:Polygon> <gml:outerBoundaryIs> <gml:LinearRing> <gml:coordinates decimal="." cs="," ts=" ">41.484375,45.703125 128.671875,-33.046875 128.671875,-33.046875 41.484375,45.703125</gml:coordinates> </gml:LinearRing> </gml:outerBoundaryIs> </gml:Polygon> </gml:polygonMember> </gml:MultiPolygon> </feature:the_geom> </feature:world2> </wfs:Insert> </wfs:Transaction> I've compared this to the GML Insert you send to TinyOWS in http://dev4.mapgears.com/bdga/bdgaWFS-T.html and it looks alike. This is the answer I received from TinyOWS: <?xml version='1.0' encoding='UTF-8'?> <ows:ExceptionReport xmlns='http://www.opengis.net/ows' xmlns:ows='http://www.opengis.net/ows' xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' xsi:schemaLocation='http://www.opengis.net/ows http://schemas.opengis.net/ows/1.0.0/owsExceptionReport.xsd' version='1.1.0' language='en'> <ows:Exception exceptionCode='InvalidParameterValue' locator='request'> <ows:ExceptionText>xml isn't valid</ows:ExceptionText> </ows:Exception> </ows:ExceptionReport> Since the update works, I suppose the saveStrategy is not the problem.
