try using another archive rather than polymorphic_archive.
Are you suggesting to drop polymorphic archive support?
try using it with xml_archive (if you have name tags) to display the archive.
I did this. The output looks ok. Here it is: <?xml version="1.0" encoding="UTF-8" standalone="yes" ?> <!DOCTYPE boost_serialization> <boost_serialization signature="serialization::archive" version="5"> <a class_id="1" class_name="B" tracking_level="1" version="0" object_id="_0"> <A class_id="0" tracking_level="1" version="0" object_id="_1"> <i>3</i> </A> </a> </boost_serialization> There is no difference in saving using xml_oarchive and polymorphic_xml_oarchive. It fails on loading the type 'B', when using polymorphic_xml_iarchive, which according to the library is an 'unregistered class'. Best regards, Christoph
