User is able to save untagged way

[danieldegroot2]

User was able to save temporary guideline / placeholder line at
https://www.openstreetmap.org/edit?way=1384443332#map=20/51.8626520/4.4748570
( is: https://www.openstreetmap.org/way/1384443332/history )

Prohibit users from saving empty / tagless objects. They should go back to select a preset / tag (key+value) first before uploading.
(see also iD / JOSM returns 'error' warning on saving changeset.)

Go Map!! 4.3.2
(iPhone); ask changeset author for details if needed

I just tested iD and it allowed me to upload an object with no tags: https://www.openstreetmap.org/changeset/166224783

But… it will also notify users during the save dialog. The "Line has no tags" error selects the line when clicked.

Not saying that I consider this something for GoMap, just that this is how iD "prevents" the error.

PS: https://ideditor.netlify.app/#disable_features=boundaries&map=20.63/52.47409/13.44565&background=Berlin-2024&locale=en has the red "live" button at the bottom that change to the dev server which can be used for testing uploads (but requires a separate user account).

I agree that iD provides warnings, but it doesn't block it outright.

iD has a great set of validations, and if we ever implement something similar then this is something that should be included.

iD removes existing objects' tags, but it still allows uploading key with empty value "*"=""). ( openstreetmap/iD#1894 )

I suppose Go Map user must have added such key with empty value.

iD does not allow uploading object without any keys/tags, however. See greyed out Upload button in tordans' example (with block icon cursor and hover text 'Resolve issues first. Open issues: 1.'.

I don't know why my session was different than @tordans but I wasn't blocked from creating an untagged way. You can look at the OSC file attached to my changeset above to verify it. But I just tried it again and it was indeed blocked 🤷‍♂️.
