I have tried to make simple sample code using Coredata
+NSTreeController+Outlineview.
My sample code is to retain order of each entities as is, and support
drag and drop.

This is first try to make coredata app...and found two strange issues.
Are they known issues?
//
a.NSTreeController remove:(id)object (Filed:4368452)
- When removing root entity object with children, I have to send
fetch request each time.
Without fetch, ghost entity appears next add/addchild operation.
b.Multiple root entities movement (Filed:4368430)
- When moving multiple root entity objects into other branch, it
crashes.
Select two root entites, drag under branch entites, it crashes.
Or, move two branch entities, into root(this works), then undo, get
crash.
//
I have used a few tricky tech's, but I guess this is not root cause.
They seem to be coredata issue. Any suggestion?
T.M.
