no, Ed's edits are lost, unless JOSM saved them to a tmp file somewhere. i think we're using different terminology - in OSM a "changeset" is a taggable group of edits, either through the REST API or the diff upload. a changeset may contain multiple edits via multiple API calls. each API call is a transaction and either succeeds or fails. this includes diff uploads - if it does not succeed an error message is returned to the client and the server's copy of the edits are discarded. the client shouldn't discard the edits (without warning the user), but it seems in this case that something went wrong - maybe the dialogue box popped under or something. cheers, matt _______________________________________________ dev mailing list [email protected] http://lists.openstreetmap.org/listinfo/dev
