making an "enabled" binding on a per-row basis in an NSTableView

Subject: making an "enabled" binding on a per-row basis in an NSTableView
From: Niko Matsakis <email@hidden>

I have a table where each row displays an items. For some rows, the item displayed is immutable, whereas other rows have objects whose fields may be edited. This is indicated by the value of an "immutable" attribute.

I would like to use Cocoa Bindings so that the immutable objects are not editable.

I have attempted to achieve this by binding "enabled" for each column to "NSNegateBoolean(arrangedObjects.immutable)", but this seems to have had absolutely no effect.

Any advice?


Thanks!
Niko
