(additionally, even ''manually'' adding extra changes in JOSM to such elements afterwards will not show any changes in `ctrl-h`) ==== What happens instead? - in step (2), JOSM shows like there are **no changes** in element whatsoever (i.e. that it is unmodified) - however, in step(3), JOSM **uploads those changes** to OSM Due to that inconsistency, user ends up confused (or even worse, oblivious) and likely ends up uploading data they though they verified, but they in fact didn't (as JOSM didn't tell them anything was modified, when in fact it was). ==== Please provide any additional information below. Attach a screenshot if possible. I'm aware that those `.osm` files are externally produced and thus the ""blame"" should be on them. However, I think JOSM should handle loading such files better: - either (preferably) accepting `.osm` files which missing `user`/`uid` and/or `changeset` attributes, and having history work correctly on them (i.e. if they are not strictly needed, which seems to be the case -- as I seem to be able to fake them with `uid=1 changeset=1` and history works then), - or throwing error when attempting to load such `.osm` files (if missing attributes are required for proper functioning of JOSM) I'll try to work with this specific tool to fix the issue at their side (i.e. produce ""full"" list of attributes), but there might be others tools which exhibit the problem without people noticing, thus JOSM fix would be nice. attached pictures: how `ctrl-h` History looks with ""full"" `action=modify` line (i.e. correctly shows modifications), vs. how it looks with short one (i.e. falsely shows there are no modifications) The problem was noticed by using this tool which e.g. on https://dina.osm-hr.org/ar/opstine/jasenovac/Trebe%C5%BE.html (when clicking on the button on the bottom and then the link, links to this [http://localhost:8111/import?changeset_tags=comment=DGU%20address%20import%20(updating%20street%20and%20housenumber)|import=yes|source=DGU_AR|source:url=https://dina.osm-hr.org|import:page=https://wiki.openstreetmap.org/wiki/Croatia/Import_addresses|source:date=24.05.2026.&new_layer=true&layer_name=Trebe%C5%BE-1-30&url=https://dina.osm-hr.org/ar/opstine/jasenovac/trebez-matched-30.osm remote control URL] {{{ Relative:URL: ^/trunk Repository:UUID: 0c6e7542-c601-0410-84e7-c038aed88b3b Last:Changed Date: 2026-03-28 20:28:41 +0100 (Sat, 28 Mar 2026) Revision:19555 Build-Date:2026-03-29 01:30:57 URL:https://josm.openstreetmap.de/svn/trunk Identification: JOSM/1.5 (19555 en) Linux Debian GNU/Linux 13 (trixie) Memory Usage: 1941 MB / 2987 MB (182 MB allocated, but free) Java version: 21.0.11+10-1-deb13u2-Debian, Debian, OpenJDK 64-Bit Server VM Look and Feel: javax.swing.plaf.metal.MetalLookAndFeel Screen: :0.0 1920x1080x[Multi depth]@60Hz (scaling 1.00×1.00) Maximum Screen Size: 1920×1080 Best cursor sizes: 16×16→16×16, 32×32→32×32 Environment variable LANG: en_US.UTF-8 System property file.encoding: UTF-8 System property sun.jnu.encoding: UTF-8 Locale info: en_US Numbers with default locale: 1234567890 -> 1234567890 Desktop environment: ICEWM Java package: openjdk-21-jre:amd64-21.0.11+10-1~deb13u2 libcommons-logging-java: libcommons-logging-java:all-1.3.0-2 fonts-noto: fonts-noto:all-20201225-2 VM arguments: [-Dsun.java2d.opengl=true, --add-exports=java.base/sun.security.action=ALL-UNNAMED, --add-exports=java.desktop/com.sun.imageio.plugins.jpeg=ALL-UNNAMED, --add-exports=java.desktop/com.sun.imageio.spi=ALL-UNNAMED] Dataset consistency test: No problems found Plugins: + DirectUpload (36474) + FixAddresses (36474) + ImageWayPoint (36474) + Mapillary (1819) + PicLayer (273) + Review.Changes (1.1.1) + apache-commons (36474) + apache-http (36474) + buildings_tools (36474) + conflation (279) + ejml (36474) + geotools (36474) + imagery_offset_db (36474) + jackson (36474) + jaxb (36474) + jna (36474) + jts (36474) + libphonenumber (9.0.31) + log4j (36474) + mbtiles (v2.8.1) + opendata (36474) + openqa (116) + osmwiki-dataitem (0.0.8) + panoramax (8) + phonenumber (1.2.0) + pmtiles (36474) + pt_assistant (682) + reverter (36474) + todo (159) + turnrestrictions (36474) + undelete (36474) + urbaneye3d (2.2.2) + utilsplugin2 (36497) + wikipedia (448) Tagging presets: + https://raw.githubusercontent.com/OpenNauticalChart/josm/master/INT-1-preset.xml + https://josm.openstreetmap.de/josmfile?page=Presets/Healthcare&zip=1 + https://.com/prezentacije/OpenStreetMap/josm-preset.xml + https://josm.openstreetmap.de/josmfile?page=Presets/Xmas&zip=1 + https://josm.openstreetmap.de/josmfile?page=Presets/GuidepostDirectionsAndDestinations&zip=1 Map paint styles: -
