have an NSTableView which is bound to an NSArrayController ; this
controller represents "accountClass" Entities. On the
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".
Sounds like you need a matching "setAccountClassesSortDescriptors"
method. Not sure why code would be trying to set that value. A
breakpoint would be illuminating. Perhaps something is bound in a way
that the array controller expects the value to be read-write.
