Yeah, this isn't going to work. It binds each row's text box to the *entire*
arrangedObjects array, which is not what you want.
If I understand your purpose, you need the Full Monty view binding procedure
"described" (if that's the right word for it) here:
https://developer.apple.com/library/mac/#documentation/Cocoa/Conceptual/TableView/PopulatingViewTablesWithBindings/PopulatingView-TablesWithBindings.html
Basically, there are two parts to this:
1. You must explicitly bind the table view's "content" binding to
arrangedObjects. Note that this normally isn't done explicitly for cell-based
table views, but it's necessary in the view-based case.
That causes the table view to set the "objectValue" property of each
NSTableCellView to the correct object in arrangedObjects -- one of your
dictionaries, in your scenario.
2. You must bind the NSTableCellView subviews to the "table cell" item in the
binding popup, and use key paths of the form "objectValue.<key>". That should
give you access to the value for <key> in the dictionary represented by
"objectValue".
FWIW, I've never actually done part 1 of this myself -- I've used a data source
for every cell-based table view I've created -- but I've done part 2 several
times and it's straightforward once you get your head around the "objectValue"
concept.
