Dear List
I am trying to build a WFS-T-application with GeoExt/Openlayers. The
features are stored in a PostGIS-DB and are served by Geoserver.
I managed to retrieve the features (as stated by HttpFox), but somehow they
won't show up in my mappanel. The code is based on the
wfs-states.html-example (http://openlayers.org/dev/examples/wfs-states.html).
I simply can't figure out why the features aren't rendered.
Here's my snippet:
Ext.BLANK_IMAGE_URL = "../ext/resources/images/default/s.gif";
>
> Ext.onReady(function() {
> OpenLayers.ProxyHost = "../cgi-bin/proxy.cgi?url=";
>
> var map_options = {maxExtent: new OpenLayers.Bounds(10000, -240000,
> 1380000, 580000),
> numZoomLevels: 12, maxScale: 5000, minScale: 2000000,
> units: 'm', projection: 'EPSG:21781'};
>
> var map = new OpenLayers.Map(map, map_options,{
> allOverlays: true
> });
>
> var modifyControl = new
> OpenLayers.Control.ModifyFeature(ogmlines); //ÄNDERN!
> map.addControl(modifyControl);
> modifyControl.activate();
>
>
> var saveStrategy = new OpenLayers.Strategy.Save({
> onCommit: function() {
> saveStrategy.ogm_lines.refresh();
> }
> });
>
> ogmlines = new OpenLayers.Layer.Vector("lines",{
> strategies:[
> new OpenLayers.Strategy.BBOX(),
> saveStrategy
> ],
> projection: new OpenLayers.Projection("EPSG:21781"),
> protocol: new OpenLayers.Protocol.WFS({

> srsName: 'EPSG:21781',
> url: 'http://localhost:8090/geoserver/wfs',
> //?strict=true
> featureType: 'ogm_lines',
> featurePrefix: 'OpenGeoMap',
> geometryName: 'the_geom',
> extractAttribute: true
> }),
> });
>

Any help is HIGHLY appreciated.
Kind regards
