Replying to simon04:
It's quite easy to run in such problems:
- Download a relation via
Download objects
, e.g., the boundary 943282
.
- Note that the members are not part of any other relation, but in fact they are (e.g., download the way
60665540
to see the second relation).
This occurred due to not using "Download referrers"
To display this warning, JOSM must be aware of potentially existing relations. I don't think that JOSM currently knows. To add this, JOSM would need to keep a history of how any object was added to the dataset. I don't think this is reasonable.
Instead, I suggest a simpler solution: Let's remove the "Download referrers" checkbox from the "Download object" dialog for the non-expert mode. What do you think?
