My goal is to have an NSOutlineView (Source List style) that contains group
items at it's root with each group item corresponding to a Core Data entity
type (which I'll hard code, it doesn't need to automatically adapt to new
entity types). I'd then like those group items to contain leaves for ever

Hi All,
I have a 10.4 style date formatter applied to an NSTextFieldCell. I
call setTwoDigitStartDate: (tried with both the epoch date and the
"reference" date) but when I type a date with a two digit year in it sets
the year to 0009 instead of 2009. Am I missing something obvious?

For some reason I didn't think to test with a style that uses a two digit
year. It works as advertised with the short style. The docs say "The

that since the medium and long styles don't have a "two-digit year

I'm no expert but one way is for the second controller's Content Array or

selection.
For example if you have an entity "Foo" with a to-many relationship called
"bars" you would:
- bind the "content set" of bars array c
Thanks for the help. The main gap in my understanding was that by default an
NSFormatter uses the same format string for converting a string to an object
and converting an object to a string. It is therefore fussy about how the
user types the string.

So Item A has link 1 as it's normal link and link 2 as it's alternate
