Still haven't figured it out yet but here's the most recent error I'm
getting
2006-05-29 09:48:39.668 QuarkXPress[2701] [<NSArrayController
0x117b9c10> addObserver:<NSSelectionBinder 0x117bfbf0>
forKeyPath:@"site.name" options:0x0 context:0x0] was sent to an
object that is not KVC-compliant for the "site" property.
Here's the accessor that shows that the target class is indeed KVC
compliant for the "site" property.
- (NSArray *) site
{
return [properties objectForKey: @"site"];
}
Here's the structure of the return from the above method
(
{id=1, name='Boston'},
{id=2, name='New York'},
{id=3, name='Chicago'},
{id=4, name='Los Angeles'},
etc...
)
I've looked at all of mmalc's examples here http://homepage.mac.com/
mmalc/CocoaExamples/controllers.html particularly the "PopUpTest"
project and I just don't see what I'm doing that is all that
different, other than his example is for shared defaults while mine
is for a popup in a dialog
I've been futzing with this for around four hours now trying every
combination of content, content + contentValues, selected values I
can think of, nothing works. What the heck am I doing wrong here?

Hi
I'm having some problems binding the contents of a popup button.
Here's what I've done so far.
1. Create a properties dictionary in my NSWindowController subclass
with the following structure
{
site = {
{id=1, name='Boston'},
{id=2, name='New York'},
{id=3, name='Chicago'},
{id=4, name='Los Angeles'},
etc...
}
}
2. create an accessor method to get the sites from the property
dictionary
- (NSArray *) site
{
return [properties objectForKey: @"site"];
}
3. In the nib file, set the custom class of the file's owner to
MyWindowController.
4. Create an NSArrayController in the nib and connect its "content"
outlet to the file owner
5. Add a "site" key to the array controller.
6. Tried binding the popup to the array controller in each of the
following ways:
- content
Bind to: PopupArrayController
Controller Key: arranged objects
Model key path: <tried leaving empty and entering "site">
-> Result empty popup
- content + contentObjects
Content:
Bind to: PopupArrayController
Controller Key: arranged objects
Model key path: <tried leaving empty and entering "site">
Content Objects:
Bind to: PopupArrayController
Controller Key: selection
Model key path: <tried leaving empty and entering "site">
-> Result empty popup
- contentValues
Bind to: PopupArrayController
Controller Key: site
Model key path: <tried leaving empty and entering "site">
-> Result empty popup
Anyone point out what I'm doing wrong here?
Thanks for any help
Ken
P.S. does anyone know of a good site that explains binding options
in detail? There's so many options for each binding property, it's
really confusing trying to figure out why they were created in the
first place and what situations call for what options.
