1782	Relation Editor overwrites all changes made to the relation from the outside	trompeter	framm	"When the relation editor is open and you split a way belonging to this relation in the JOSM main window, the splitted part of the way looses the relation when closing the relation editor with OK.

I think I know why it is like that:
1) When opening the relation editor a copy of the relation elements is generated for editing.
2) The split in the main window splits the way in two parts and adds the second part also to the relation. However, the relation editor is not notified about this change.
3) When closing the relation editor, the copy of the list of elements is written back to the data set, overwriting the change which had been made in the main window.

This behaviour is annoying and easily leads to errors in the relations. Currently I think of two possiblities to improve the situation:
1) Issue a warning or error when this scenario occurs
2) Add a notification mechanism to apply the split in the main window also to the data set in the relations editor."	defect	closed	major		Core	latest	fixed	relation split	Gubaer
