Question

I have a NSArrayController bound to an NSTableView so the table column like the following:

NSTableView bindings:
Content -> ArrayController.arrangedObjects
SelectionIndexs -> ArrayController.arrangedObjects
SortDescriptors -> ArrayController.sortDescriptors

NSTableColumn bindings:
Value -> ArrayController.arrangedObjects.description

When I try and sort it using the column header it just crashes with something like

error setting value for key path sortDescriptors of object NSArrayController

Any ideas?

Let me suggest you a simple way to do this –

NSTableColumn bindings:

Value -> 

Bind to: ArrayController

Controller Key : arrangedObjects

Model Key Path : keyPath (such as name)
