EDIT

This exception does not appear if it is called without the monitoring thread. As a workaround the monitoring thread is removed and we have to find a new solution with monitoring

now this problem also appears whithout the progress monitor.

Hallo,
habe versucht, für die ganzen Apocynaceae in Fl. Cuba die sec. Ref. zu ändern, Fehler.
Funktioniert auch für nur eine Gattung nicht.

This seems to be a problem when the setSecundumForSubtree method was called with the same reference before.
