Cannot delete empty relation

[jfd553]

What steps will reproduce the issue?

1. I am not sure about the initial state. Probably deleting all relation components without editing the relation (opening the relation’s editing window).
2. Run the validator, which reports empty relations.
3. Try to delete the empty relation.

What is the expected result?

I used to be able to delete empty relations.

What happens instead?

A warning stating “The operation was not performed, according to the delete_outside_nodes preference”.

So, I can't delete the empty relation, since its components are deleted. I don’t want to send back an empty relation to OSM, but closing JOSM without saving changes, I will lose hundreds of edits I made.

Please provide any additional information below. Attach a screenshot if possible.

IFAIK, the empty relations shown by the Validator come from a wooded island inside an intermittent water body that I deleted.

I haven't been able to reproduce.

Can you save and upload? And give us the id of the relation you were trying to delete?

[jfd553]

Saved and upload done

Empty relations I can't delete:
12595883 - natural=water
12595884 - natural=wood

[GerdP]

I can reproduce the error when I save a downloaded relation to file and open that file. If I then try to delete the relation I get the same message. Obviously the error message is misleading.
