What is the expected result?

Well, that I'd be able to add an attribute.

What happens instead?

I get this exception :

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

It also does that when I try to change something from an existing relationship.

Hum, I just updated to 3354 and it seems to be fixed, so, I'll close…
Sorry for the noise.

[Mathieu Arnold <josm@…>]

Ok, no, it's not fixed in 3354, so, I'm reopenning it.

Please submit an example file (as small as possible) where this happens and what you need to do to get it happen.

[Mathieu Arnold <josm@…>]

Ok, you'll need the AddrInterpolation plugin.

so, download something somewhere, doesn't matter.

• create a street, say, unclassified, give it a name.
• create a way with at least three nodes along that street.
• select both ways.
• Tool/Address interpolation.
  • tell it to create a relation
  • give the start and end numbers, say, 1 and 5.
  • check the box at the bottom so that it converts the way into nodes.

After those steps there's a good chance that if start clicking around (yes, very scientific, but well, that's what I do) and then, try to edit the relation, you'll get an exception.

You'll also definitively get exceptions if you try to undo the last step.

Fixed in plugin 23420 - reorder addr interpolation way to avoid loss of referential integrity
