I've run into this before and in my case it was because I forgot to 
bind the Selection Index Paths of my Outline View Content to the 
selectionIndexPaths key path of my tree controller. Forgetting this 
setting caused additional problems like insert: inserting after the 
last-created entry instead of where the selection in the UI was.

Do you have this binding set on your outline view?
