Hi all,
Can someone please tell me whats missing from my code to get WFS-t to commit changes.
The demo works fine and my example works fine up to saving changes to file when an extra line is added.The data is added from postgreSQl database with PostGIS.

var roads = new OpenLayers.Layer.WFS(
“Track”,
“/geoserver/wfs”,
{typename: ‘topp:ttlines’},
{
typename: ‘topp:ttlines’,
featureNS: ‘http://www.openplans.org/topp’,
extractAttributes: false
}
);
roads.style = OpenLayers.Util.applyDefaults({strokeColor: “#ff0000”},
OpenLayers.Feature.Vector.style[“default”]);

map.addLayers([tiled, untiled, roads]);

var panel = new OpenLayers.Control.Panel(
{displayClass: ‘olControlEditingToolbar’}
);

var drawLine = new OpenLayers.Control.DrawFeature(
roads, OpenLayers.Handler.Path,
{displayClass: ‘olControlDrawFeaturePath’}
);
drawLine.featureAdded = function(feature) {
feature.layer.eraseFeatures([feature]);
// cast to multilinestring
feature.geometry = new OpenLayers.Geometry.MultiLineString(
feature.geometry
);
feature.style.strokeColor = “#ff0000”;
feature.state = OpenLayers.State.INSERT;
feature.layer.drawFeature(feature);
}

panel.addControls(
[new OpenLayers.Control.Navigation(), drawLine]
);
map.addControl(panel);
map.addControl(new OpenLayers.Control.LayerSwitcher());
map.zoomToExtent(
new OpenLayers.Bounds(2629421.7940751617, 6192776.755018141,
2633541.55790017, 6195366.924973875)
);
}

Do you really want to write changes to a file? Don't you want to save it back
into PostGIS database?

For writing changes back to the database, I added a new
OpenLayers.Control.Button. When this is pushed all changes to the layer will
be written via WFS-T to the database. Maybe this could help you:

wfs = new OpenLayers.Layer.WFS(
        "Rohr-Graben-Damm",
        "http://beige.rgb:8080/geoserver/wfs",
        { typename: 'topp:rohre_graben_damm' },
        {
            typename: 'rohre_graben_damm',
            featureNS: 'http://www.openplays.org/topp’,
            extractAttributes: false,
            commitReport: function(str) {
                storage.removeFeatures(storage.features);
            }
        }
    );

var save = new OpenLayers.Control.Button({
        trigger: OpenLayers.Function.bind(wfs.commit, wfs),
        displayClass: "olControlSaveFeatures"
    });

            var roads = new OpenLayers.Layer.WFS(
                "Track",
                "/geoserver/wfs",
                {typename: 'topp:ttlines'},
                {
                    typename: 'topp:ttlines',
                    featureNS: 'http://www.openplans.org/topp’,
                    extractAttributes: false
                }
            );
            roads.style = OpenLayers.Util.applyDefaults({strokeColor:
"#ff0000"},
                    OpenLayers.Feature.Vector.style["default"]);

            map.addLayers([tiled, untiled, roads]);

            var panel = new OpenLayers.Control.Panel(
                {displayClass: 'olControlEditingToolbar'}
            );

            var drawLine = new OpenLayers.Control.DrawFeature(
                roads, OpenLayers.Handler.Path,
                {displayClass: 'olControlDrawFeaturePath'}
            );
                drawLine.featureAdded = function(feature) {
                feature.layer.eraseFeatures([feature]);
                // cast to multilinestring
                feature.geometry = new OpenLayers.Geometry.MultiLineString(
                    feature.geometry
                );
                feature.style.strokeColor = "#ff0000";
                feature.state = OpenLayers.State.INSERT;
                feature.layer.drawFeature(feature);
            }

            panel.addControls(
                [new OpenLayers.Control.Navigation(), drawLine]
            );
            map.addControl(panel);
            map.addControl(new OpenLayers.Control.LayerSwitcher());
            map.zoomToExtent(
                new OpenLayers.Bounds(2629421.7940751617,
6192776.755018141, 2633541.55790017, 6195366.924973875)
            );
        }
