Could I be doing something wrong, or is this some kind of bug? And do I have to somehow translate column 0 to find out the real column? I know Java tables have methods to translate between model and view column numbers because of user reordering, but I haven't noticed such a thing in Cocoa.
Yes, you're doing something wrong. You are assuming that column 0 is always a specific column, which because of user reordering, is not the case.
Instead of hard-coding 0 as the index of the column, look up its index by [NSTableView columnWithIdentifier:@"foo"]; The identifier is what identifies the column, not its index, so you have to look up the index dynamically.
