<br><div class="gmail_quote"><br><br>Dear List<br>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.<br>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 (<a href="http://openlayers.org/dev/examples/wfs-states.html" target="_blank">http://openlayers.org/dev/examples/wfs-states.html</a>). I simply can't figure out why the features aren't rendered.<br>
