Hi,
I've a NSSegmentedControl, 7 segments (labeled with weekdays), which
has selectedIndex bound through a value transformer (NO reverse
transformation) to NSDates.
Now, one of my awakeFromNib do this:
[sedutaDays setTarget:self];
[sedutaDays setAction:@selector(setWeekDay:)];
[sedutaDays setContinuous:YES];
setWeekDay: essentially change the day of the NSDate which
NSSegmentedControl is bound to, by accessing the NSArrayController,
selectedObjects:, objectAtIndex:0, and so on..
The problem is that my setWeekDay: action is sent only if I click
the selected segment (set by binding), clicking on any of other 6
segments results in an attempt to reverse transform the value, which
obviously fail with "[NSCFNumber timeIntervalSinceReferenceDate]:
unrecognized selector sent to instance 0x1019a40" since my value
transformer doesn't reverse..
Any idea why it seems that only selected segments has setAction: ?
Passed two last days trying to understand why my NSSegmentedControl
has this behavior but nothing came out.. I'm very disappointed..
