Hi Bernd, The GML2 and GML3 encoder use completely different technologies... so figuring out the issue can be tricky.
However in this case what is happening (and this is a very bad error messsage), is that an element in the schema can not be found. Looking at the DescribeFeatureType output for the umwelt2 layer i see this: <xsd:element name="FeatureOfInterest1_iSPACE001" substitutionGroup="gml:_Feature" type="gml:umwelt2Type"/> Which struck me as unusual... usually its the lement is named "umwelt2". So it seems that your datastore is creating the typename "FeatuerOfInterest..." but GeoServer is expecting it to be "umwelt2".
