The exception I was getting was from a binding established in IB, which
is a bit of a worry, but it prompts me to ask whether I'm pursuing the
right road.
What I have is an NSTableView (still cell-based, moving to view-based is
further down the track), and then a bunch of buttons that need to be
enabled only when there is a selection in the table. Binding to the
selection property of the array controller with NSNotNil doesn't work.
Binding to selectionIndexes.count (which works as 0 or 1) does work, but
this is the binding where I get the exception. Finding that binding was
trial and error, as I haven't really found a good guide to this whole
area, so I would be happy to have a better solution.
