Hello Joshua Thanks a lot for your answer and idea.
We found out another problem: we import our data by FME. Importing the data without any special specifications to PostGIS the geometry-type "multipolygon" will be assigned (for polygon features). We don't need the data to be "multipolygon" so trying out some things we transferred them to normal "polygons". Applying my same SLD once more to these data the attribute-based color works fine. There seems to be a problem in the combination Geoserver - multipolygons and attribute-based displaying of the data. In our case the problems were showing mainly in donut-objects. Is this a known problem with Geoserver? Will this be fixed? Kind regards Lisa Joshua M.
