Hi Donald
I can't see anything wrong with the code. Could it be that NodeComparator
compares the names of hte documents as well? (A document has a name). Maybe
we should patch NodeComparator to not use the document name in the
comparison.
You can test if this is the issue by....
Document doc1 = ...;
Document doc2 = ...;
doc1.setName( "foo" );
doc2.setName( "foo" );
if ( comparator.compareTo( doc1, doc2 ) != 0 ) {
... failed...
