@james2432 Changing all the id=-1 doesn't solve it, now all of the features converge into a single node.
I think this issue is with JOSM and not geojson2osm, this project has been forked many times.

1st: https://gist.github.com/tecoholic/1396990 written by @tecoholic
2nd: https://github.com/aaronlidman/osm-and-geojson written by @aaronlidman

I'm sure they have valid reasons why the XML is in this format.

[james2432]

@DenisCarriere No the id should be incremental... -1 -2 -3 -4 -5 -6.... but the changeset attribute is the problem. it should have instead action='modify'

TL;DR : replace changeset="false" with action='modify'

Changeset should only be set to a positive integer when it has been uploaded to the OpenStreetMap database

[DenisCarriere]

@james2432 Oh that makes sense, i'll test it out.

[DenisCarriere]

This "patch" works for my particular use case.

geojson2osm(geojson).replace(/changeset="false"/, 'action=\"modifiy\"')
