Model Key Path issue with view-based NSTableView

Question

When setting up bindings to work with NSTableView I'm coming across a problem. My array controller is bound to my table controller and its model key path is the array I'm using to populate the table. I've also set up one key, called name.

My table view is bound to my array controller and the Controller Key is set to arrangedObjects. Finally, the NSTextField is bound to the Table Cell View, and this is where the problem lies. When I try to input my model key path, I can input objectValue, however when I go to add .name I get a 'No completions found' tooltip appear.

Why is my key not being pulled through to the NSTableView binding?

I should add I've followed the Apple documentation to the letter however it still doesn't pull through my key.

Answer 1

The intermediate TableCellView object is "breaking" the link between the key you added to the NSArrayController and your controls. I wouldn't worry about it. If you know the keyPath is correct, just enter it, even if there's no auto-completion. It would be nice if Xcode were smart enough to automagically bridge that gap, but I don't consider it a "red flag" that it doesn't. I've certainly had plenty of cases that work just fine despite auto-complete not filling in the key.
