All OK, but the tableViewSelectionDidChange: delegate method isn't called in this instance. In a way, I can see that it's not the user changing the selection, but the problem becomes that now the inspector is still pointed at an object, but there's no selection, and the logic goes badly wrong.

If you are otherwise getting delegate calls when you manually (i.e. NOT programmatically) change the selection, then you are running into the situations where notifications are not sent when programmatic selection changes are made. The only way around this is to watch directly for selection changes, which you may be able to accomplish either by observing selectedRowIndexes of NSTableView or selectionIndex(es) of an NSArrayController that the table view is bond to.
