Hi Luc,

I have an NSArrayController that has bindings to another
NSArrayController:

A1 Content Set -> A2

When the selection changes (single selection) in A2, arrangedObjects
in A1 returns the correct number of objects but if I do a multiple
selection in A2, then arrangedObjects in A1 returns nothing. Does this
has to do with "Content Array for Multiple Selections"?

I'm fairly new to Core Data and can't find info about this.

This is purely a Cocoa Bindings question. You might try starting with the Cocoa Binding Programming Guide. Multiple selections can behave a little differently.

- Ben
