Dietrich, a spatial filter can be obtained using WFS filter encoding [1] with spatial operator BBOX in your server URL. It works fine! > 2) In the Modeler of Sextante some tools are deactivated.

You have simply to add at least one input vector layer to activate their corresponding tools into modeler. > 3) Using the vectorize tool for polygons from Sextante, I got some > problems for complex polygons, i.e. polygons with holes.
