IllegalArgumentException: "Relation member cannot be null" after upload while relation editor open

[dieterdreist]

Happened after upload. I had a relation editor window open, uploaded, and after successful upload hit "OK" to close the relation editor.

Can you reproduce this?

[anonymous]

I cannot fully reproduce this at the moment, but there is some inconsistency in the relation editor. E.g. a multipolygon relation, 1 outer, 1 inner way.

1. open the relation editor for the relation
2. split the outer way in 2 in the map view
3. the relation editor shows only 2 members but the properties in the main view show membership in a relation with 3 members
4. hit OK in the relation editor (note that the relation still has only 2 members in this editor)
5. reopen the relation editor: it now has 3 members

same goes for the other way round (combine e.g. the 2 outer members from the example above, keep one, remove the other, the relation editor after this still shows 3 members, one closed outer (changes on combine) and one open outer (version 0, 0 nodes, id:0). After closing and reopening this is resolved.

Btw.: It seems that it is not possible any more to open more than one relation editor window for the same relation (this solves some issues and AFAIR at least for some time this was possible).

seems as if the initial problem is gone (or at least I cannot reproduce it, maybe just happens occasionally).

[stoecker]

Generally we miss a realtime announcement for changes outside the relation editor. That it does not cause trouble in your example probably is caused by the fact, that you did not modify the relation between step 2 and 5.
