Awesome! Thanks for the help....I was starting to think that by hiding
the difficult stuff from you, bindings also limited you from doing what
needed to be done. But I can do what I need to do in code, like you've
shown me here.
Thanks again!

The problem is that a change on the preference panel only ripples
through to the column of the table view when I change the value in
the table view (and it then tries to reapply the transformer which
gives the correct dynamic NSColor). I would like a change to ripple
through to the text color immediately upon change in the preference
panel.
Either register for preferences change notifications, or (probably
better), observe user defaults:
- (void)awakeFromNib
{
[[NSUserDefaultsController sharedUserDefaultsController]
addObserver:self
forKeyPath:@"values.favoriteColor" // whatever key
options:0
context:favColorContext];
}
- (void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object
change:(NSDictionary *)change context:(void *)context
{
if (context == favColorContext)
{
[tableview reloadData];
}
// If appropriate: [super observeValueForKeyPath:(NSString *)keyPath
ofObject:(id)object change:(NSDictionary *)change context:(void
*)context];
}
I should probably update the Preferences example to follow this
pattern...
