In a document based Tiger (10.4.11) app I have
@interface MyDocument : NSDocument
{
NSMutableArray *things;
}
Inspector.nib has an NSObjectController with content = current
MyDocument
and an NSTextField with value bound to [EMAIL PROTECTED]
When the Inspector gets loaded I get:
... [<NSCFArray 0x3a6400> addObserver:forKeyPath:options:context:] is
not supported. Key path: @count
Workaround:
implement in MyDocument:
- (unsigned int)countOfThings { return [ things count ] }
and bind NSTextField to selection.countOfThings.
Why does @count not work? What am I doing wrong?
Kind regards,
Gerriet.
