2953	[PATCH] Sorting a relation adds new members or crashes	R2D2_C3PO	Gubaer	"Version: 1788
I was trying to sort relation 31508 usings JOSM's sort function.
First I had not all members downloaded and it failed with this exception:
java.lang.NullPointerException
	at org.openstreetmap.josm.gui.dialogs.relation.RelationNodeMap.remove(RelationNodeMap.java:99)
	at org.openstreetmap.josm.gui.dialogs.relation.GenericRelationEditor.sort(GenericRelationEditor.java:384)
	at org.openstreetmap.josm.gui.dialogs.relation.GenericRelationEditor.access$700(GenericRelationEditor.java:106)
	at org.openstreetmap.josm.gui.dialogs.relation.GenericRelationEditor$9.actionPerformed(GenericRelationEditor.java:333)

Of course sorting can't work when not all members are downloaded but a message telling the user about the problem would be better than an expection.

After downloading all members I tried to sort again. Each time I click the sort button the number of members increases. This should not happen. Sort has to reoder the existing members, not to add any new (even if they are duplicates)."	defect	closed	major		Core	latest	fixed	relation, sort	Gubaer
