The latest (20150602)
FBDK2 self-update now supports DnD tagging of FB instances in the
Tagged Data Design Pattern. See the documentation at
http://www.holobloc.com/doc/despats/tags/tags.htm#Tools for details.
Previous versions of the FBDK tried to support automatic application of tags under certain conditions, but this turned out to result in unanticipated and sometimes undesirable results.
