Unfortunately my numberOfRowsInTableView is being called 'before'
awakeFromNib, so initially numColumns = 0 and I get an error
(myDataSize/numColumns will be infinite).
So set a flag in -awakeFromNib. Check this flag in
-numberOfRowsInTableView: and return 0 if this flag isn't set.
I always thought awakeFromNib would get called first. But in this
case not
so. So can anyone suggest why, and a workaround?
The order of -awakeFromNib calls is not guaranteed. In fact, you
probably have an outlet from your tree controller to your table view,
so the table view must necessarily be awoken first, since all outlets
are guaranteed to be set up before -awakeFromNib is called.
NSTableView's -awakeFromNib probably causes it to probe its delegate.

Yes, that makes sense - there is an outlet.
At least I know its not my code.
Thanks!
