19913	IOOBE: Index 254 out of bounds for length 0: Saving a relation, after splitting a child member with open relation editor	skyper	GerdP	"This is a follow up of #19353. Sadly, the situation is not much better.

==== What steps will reproduce the problem?
1. Have a relation editor with some ways as member of the relation
1. Split one way
1. Change the order in the memberlist
1. Save relation

==== What is the expected result?
After 2. the refesh button should be active an autorefresh is needed.
After 4. the relation should be saved without problem.

==== What happens instead?
After 2. the new way is not in the memberlist of the relation editor
After 4. a conflict and an exception similar to #19055.

==== Please provide any additional information below. Attach a screenshot if possible.
It seems I do not get around the conflict at all, as the reload is not possible. Strange.
