I have an NSTableView which is bound to an NSArrayController ; this

NSArrayController, I have a sort descriptor bound to a function
(called accountClassesSortDescriptors) that returns an array of
NSsortDescriptors (actually, there is just one sort descriptor in
this array right now; I initialized it with initWithKey:
@"accountClass" ascending: @"YES").
My data is sorted correctly when the table view is displayed,
however as soon as I click a column header I get an error message in
the log : "Error setting value for key path
accountClassesSortDesciptors of object <blablaController> ... this
class is not key value coding-compliant for the key
accountClassesSortDescriptors".
When you click the table column, the sort descriptors are updated.
Since you've bound 'sortDescriptors', the array controller now
attempts to update the value to which you've bound it...
(Ben then shows the solution...)
