I have an NSTreeController bound to a core data instance. This
seemed to work well with simple testing. I can add items to the
controller, and I can add children to an item (children are the same
entity). But I just noticed that when a child is selected, and you
click add, the entity is added at the same level as the selected
entity (to its parent). Where as the functionality is correct, I
didn't know that that was what it was.
The other thing I noticed was that sometime when I do this - call
add when a child is selected - or, when I call addChild when a child
is selected - the log displays the following method when save is
called (in this case save writes the data to disk):
2005-12-07 21:07:25.532 MyApp[1137] Can't reassign an object to a
different store once it has been saved.
Even stranger, when I then exit the app (which calls save again)
sometime the message is repeated, and sometimes it is not. When it
is not repeated, the item actually gets saved. When it is repeated,
the item does not get saved.
I am also not using more than one store in my app.
Any ideas?
