Never mind. I figured it out.

Hi
I have an NSArrayController bound to an NSArray and am not getting
notifications either through my "setXXX method or through explicit
"addObserver" links.
The property in my class is defined like so:
@interface PMXMainPaletteToolbar : NSView
{
IBOutlet NSPopUpButton *site;
NSDictionary *siteRecords;
NSString *currentSite;
NSArrayController *siteController;
}
The array controller is initialized like so
- (void) initTools
{
siteRecords = [[PMInterfaceController invocation]
invokeWithSelector: @"get_sites_simple" arguments: @""];
siteController = [[NSArrayController alloc] initWithContent:
siteRecords];
// bind popup content to array controller array (This works. Popup
is populated correctly)
[site bind: @"content" toObject: siteController withKeyPath:
@"arrangedObjects.name" options: nil];
// even though class has a currentSite property, a currentSite
method and a setCurrentSite method
// the setCurrentSite method is never called when bound to the
array controller
[self bind: @"currentSite" toObject: siteController withKeyPath:
@"selection.name" options: nil];
// When above binding failed, I tried to explicitly define a
listener to the "selection" and "selectionIndexes" property of
siteController
// but neither observer gets called in response to menu selections.
[siteController addObserver: self
forKeyPath: @"selectionIndexes"
options: NSKeyValueObservingOptionOld |
NSKeyValueObservingOptionNew
context: NULL];
// When both of those failed, I tried to listen for the
selectedValue of the popup
[site addObserver: self
forKeyPath: @"selectedValue"
options: NSKeyValueObservingOptionOld |
NSKeyValueObservingOptionNew
context: NULL];
// that failed as well. My "observeValueForKeyPath" is never called.
}
So the question is, how the heck does one get real time
notifications to user selections in a popup menu?
Thanks for any help
