I'm stumped. My Swift app uses an NSTableView bound to an array controller, and uses a bound NSSearchField as a text filter. My problem is that the table's selectionIndexes binding gives me the selected indexes in the filtered table, whereas I need the selected indexes in the unfiltered table.
Example... my table has 1000 rows and I want to select row 567. Rather than scroll down to row 567, I enter a few characters into the search box, and this reduces the number of rows to 17, and the row I'm interested in is now row 12. If I select row 12, how can my app figure out that row 12 corresponds to row 567 in my data array?
selectionIndexes of NSArrayController are indexes in arrangedObjects of the arrayController. arrangedObjects is the content of the arrayController, filtered by filterPredicate and sorted by sortDescriptors.
