NSPopUpButton bindings bug
-
If a NSPopUpButton is directly bound to an immutable array (no indexed
accessor methods), such as:
content = "model.anArray"
contentValues = "model.anArray.string"
It behaves as if the contentValues were bound like this:
contentValues = "<model.anArray....>"
...because the button will not create items for duplicate strings in
the array. Should I file a bug? Is there a workaround?

the same, how would the user discriminate between them?

Shouldn't that be up to the developer to decide? I feel it most
certainly IS an API bug (as well as a documentation bug). If I have an
array of 10 elements to display, which results in the bound
NSPopUpButton showing only 7 items... ahem. If I required a
@distinctUnionOfObjects, I would have specified a
@distinctUnionOfObjects. Isn't that the reason for having KVC array
operators?

OT: today was the first day that Bug Reporter remembered my Apple ID
on the web form! Maybe someone is finally working on tuning up
RadarWeb? ;)

By their position in the menu? Consider a menu like this, where the app
names are grayed out (a contrived example, I know):
iTunes
Play
Pause
Mute
-----------
iMovie
Play
Pause
Mute
-----------
GarageBand
Play
Pause
Mute
_murat

I can't find any workaround at the moment. I would suggest finding a
way to ensure each string is unique.> rdar://problems/3777252Please try to file different bugs in different reports (behaviour vs.
