[josm-dev] visible vs. deleted

[Matthias Julius]

Hi all,

The API only has a visible flag to indicate deleted objects.  Yet, on
conflict JOSM is presenting this in the Resolve conflicts dialog:

  My version                  Their version   

  deleted                     not deleted
  visible (on the server)     not visible (on the server)


I have a hard time making sense of this.

I guess this happens when trying to delete a deleted object.  But why
does JOSM make a distinction between deleted and visible when the API
doesn't?

What this comes down to is the question what JOSM should do when
during data update it finds that an object it has marked for deletion
is already deleted on the server.  I think it should be safe to just
remove those objects from the dataset.  After all it is not really a
conflict when the JOSM user and the API both think that something
should go away.
