[Users] Building a WFS-T-application; Problem rendering WFS

[andreia farrér]

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:
