[josm-dev] JOSM, the relation killer

Hi,
every now and then we have isolated reports about all members of a
relation having accidentally been removed with JOSM.
Just recently, with JOSM 3097, someone made this changeset
http://www.openstreetmap.org/browse/changeset/4238359
in which this 2700 member relation
http://www.openstreetmap.org/browse/relation/18162
(which has meanwhile been deleted and re-created as #544296) was robbed
of all its members; only the empty, tagged relation remained.
The user says that he had not changed the relation except removing a
node from a way that was part of the relation; then, on upload, that
edit produced a conflict which he resolved by saying that the deletion
of the node can be ignored.
I don't have details but I have a feeling that some sort of conflict
resolution was involved in most of these "help, JOSM has removed all
members from the relation" problem.
I'll play around a bit on then dev API and see if I can reproduce the
problem.
Bye
Frederik
