Hi,
Here is the problem :
java.lang.NullPointerException
at
org.geotools.xml.gml.GMLComplexType$AbstractFeatureCollectionType.encode(GMLComplexTypes.java:4778)
at
org.geotools.xml.DocumentWriter.writeFragment(DocumentWriter.java:310)
at
org.geotools.xml.DocumentWriter.writeDocument(DocumentWriter.java:208)
I use the library 2.3.1.
Thanks,
Florian.

Hi,
The code to copy the feature looks fine. A couple of questions. Exactly what
