Hi,
Sorry maybe i should have clarified that but i believed that Quincey
had already explained about the datasource methods. You *must* (if you
dont want to end up in a heap of self-inflicted mess) represent your
data in those way - WHEN you intend to link to an NSTableView using
bindings.

I posted a number questions to this discussion list. They were all

Yes. You can use Core Data in pretty much any situation where you

is too restrictive, you might want to think about falling back to
the pre-bindings way of populating a table view: the data source.
Yes, noted.

Hello,
I am stuck finding a solution for my array of arrays problem. - A
problem with a twist !
For the data must be displayed in an NSTableView and therefore it must
be structured in a particular way.
Mutable array of [items] with keypaths in each item making up the
columns of each row
hen -someMethod has side effects :).
Did you step through it in gdb to see what was going on?

Often people see "delegate method" in the Cocoa documentation and
believe they cant use those ones because it requires a special object
that they dont have.
However delegation is a very useful programming method.
Usually another developer writes a library class that requires a
