I have a tableview who's enabled binding is bound to a
NSArrayController (not the one that feeds it via its content
binding). I'd like to be enabled when something is selected and
disabled when it is not. So far I've been unable to find a suitable
key to bind to on the array controller. It seems like you should
just be able to bind to selection with the NSIsNotNil value
transformer and set the correct placeholder options, but apparently
this doesn't work. I've tried various combinations of selection and
selectedObject with and without the NSIsNotNil value transformer, but
they don't change the view's state at all and most of the
combinations kick back nasty bindings error. I should also note that
the array controller that feeds the data to this tableview is itself
fed from coredata.
Anyone gotten something like this to work?
