Hi all,
I already have sent this problem to tinyows list but according to their
information, it seems to be a client side problem so I am forwarding it to
this list to see if I can get some support.
I am trying to implement WFS-T support to Mapserver so I am using TinyOWS
1.0. Requests are being made to server and it seems to work correctly, I am
getting a correct xml response. Anyway, features are not being displayed on
an Openlayers implementation.
Here is my tinyows.xml
<tinyows online_resource="
http://molleresdevel.eurogeotecnica.com/cgi-bin/tinyows"
schema_dir="/usr/local/share/tinyows/schema/"
log="/tmp/tinyows.log"

<metadata name="TinyOWS Server"

<contact name="TinyOWS Server"

<layer retrievable="1"

</tinyows>
And here you can see my openlayers code which is very close to this example
http://openlayers.org/dev/examples/wfs-protocol-transactions.html
<script type="text/javascript">

this.layer = layer;
this.handler = new OpenLayers.Handler.Feature(
this, layer, {click: this.clickFeature}
);
},
clickFeature: function(feature) {
// if feature doesn't have a fid, destroy it
if(feature.fid == undefined) {
this.layer.destroyFeatures([feature]);
} else {
feature.state = OpenLayers.State.DELETE;
this.layer.events.triggerEvent("afterfeaturemodified",
{feature: feature});
feature.renderIntent = "select";
this.layer.drawFeature(feature);
}
},
setMap: function(map) {
this.handler.setMap(map);

},

....
So as I said, it seems to get a proper response.
Any help will be sincerely appreciated.
