Thanks for the advice, Bart. I altered my code with the "featurePrefix" but the result is still the same, no feature showing up in my map. Is it possible, that the style of the feature could be somehow jinxed, e.g transparent? Or could there be any other reasons. It's my first openlayers-project and I've been trying for days now. Kind regards Andreia

That's the namespace which is bound by Geoserver to the OpenGeoMap prefix. Best regards, Bart -- Looking for flexible support on OpenLayers or GeoExt?

First I created a polygon-shapefile (one polygon in it, extending a big part of eastern Switzerland) in QGIS and imported it into my PostGIS-DB as "ogm_polygons"; then I published the layer in Geoserver. Now I would like to show the polygon-features in my map which somehow doesn't function.
