Hey list,
A binding is driving my app (my actual one, not the test one) and has been for
days now--awesome! Amid more refactoring of my code, and adding a second
binding which didn't take because of uninitialized properties, I've now started
seeing this error in my debug log:
[_NSControllerObjectProxy copyWithZone:]: unrecognized selector sent to
instance 0x608000000ae0
failed to set (contentViewController) user defined inspected property on
(NSWindow): -[_NSControllerObjectProxy copyWithZone:]: unrecognized selector
sent to instance 0x608000000ae0
From what I've been reading, this is due to something trying to copy an object
that doesn't conform to the NSCopy protocol. Most likely, I have a proxy object
somewhere Cocoa expects an instance, and since the proxy can't be copied, this
is happening. The problem is, I can't see *where* this is going on. My debug
log is showing me this, but my debug navigator is empty. There's no runtime
error showing in a source file like there is when the line causing the problem
is clear, and since I only have an address for the instance and not a name, I'm
at a bit of a loss. What is a good strategy for discovering the source of this
problem so I can fix it?
In case this affects things, I'm seeing the following at the very top of my
debug log:
Failed to connect (tweetTextField) outlet from (Cinnamon.ViewController) to
(NSTextView): missing setter or instance variable
This is, I'm pretty sure, because tweetTextField is gotten via a computed
property, pulling the documentView out of a scroll view; as it says, I have no
setter. This setup was working before I managed to cause the afore mentioned
copying problem, though, so I doubt this is related. Better too much detail
than not enough, though. My declaration for this is:
@IBOutlet weak var tweetScrollView:NSScrollView!
var tweetTextField:NSTextView { //all we need here is the text view
inside the scroll view
get {
return tweetScrollView.contentView.documentView as!
NSTextView
}
}
Anyway, any suggestions on how to hunt down the cause of this copying bug would
be appreciated. Thanks everyone!

Have a great day,
