[mapserver-users] TinyOWS insert feature not working

Hi, Thanks for the sample wfs link and for the Kosmo GIS suggestion.
I found a temporary workaround for my problem.
In the tinyows.xml file I added a setting: check_schema="0". Now adding new
features works like charm with OpenLayers and with QGIS.
So, it seems that my error is somehow related to "schema validation". When
I looked at my insert request, I found that the xsi:schemaLocation is
different from your example. In my error case it is:
1. 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"
But in your working example it is:
xsi:schemaLocation="http://www.opengis.net/wfs
http://schemas.opengis.net/wfs/1.0.0/WFS-transaction.xsd
http://hip.latuviitta.org/cgi-bin/tinyows?SERVICE=WFS&REQUEST=DescribeFeatureType&version=1.0.0&TYPENAME=lv:editable_multipolygons&NAMESPACE=xmlns(lv=http://latuviitta.fi/)<http://hip.latuviitta.org/cgi-bin/tinyows?SERVICE=WFS&REQUEST=DescribeFeatureType&version=1.0.0&TYPENAME=lv:editable_multipolygons&NAMESPACE=xmlns(lv=http://latuviitta.fi/)>
http://latuviitta.fi/"
So, it seems that I'm missing some parts of the xsi:schemaLocation
attribute such as TYPENAME and NAMESPACE.
Any ideas what the xsi:schemaLocation means? Is this somehow related to the
schema_dir, ns_prefix and ns_uri settings in my tinyows.xml file? I'm
really quite confused what the schema, prefix and namespace in the wfs come
from.
