Hello again,

If I try to sort a FeatureCollection, I get a null FeatureList.
So I do:

  final FeatureCollection fc = source.getFeatures(filter);

and this returns my feature collection (an instance of
JDBCFeatureCollection to be precise).  Good.  But:

  final SortBy      rt = ff.sort(sortField, SortOrder.DESCENDING);
  final FeatureList fl = fc.sort(sort);

this returns a null FeatureList (ff is the FilterFactory).  Hmmm.
To figure out why, I looked into these three classes (gt2-2.4-M4):

  library/jdbc/src/main/java/org/geotools/data/jdbc/JDBCFeatureCollection.java
  
unsupported/h2/src/main/java/org/geotools/data/jdbc/collection/JDBCFeatureCollection.java
  library/main/src/main/java/org/geotools/feature/DefaultFeatureCollection.java

and I was a bit disappointed.  Is sorting supposed to work or is it a
future enhancement?

Regards,
