I've been using the technique suggested here by Mike for quite some
time and have a very bizarre situation. When scrolling through the
NSTableView (using the up / down arrows) the displayed (or rather
selected index) of some of the popups changes. For instance, as I
scroll down through the list and pass row 10, the selected popup
index changes from 2 to 0. Then when I scroll back up the list, the
selected popup index changes back. I've dumped out the values being
returned from objectValueForTableColumn and the returned values are
constant (in other words, the index being returned for that column on
row 10 is always 2. And if you click on the popup button, the
correct index is selected.
Is there an issue sharing the same instance of an NSMenu among many
rows?
Thanks.

If all the rows should be popups, but the items in the popup must
differ then you actually have a second choice which might be
simpler if
you haven't already got a suitable NSTableColumn subclass...
Since the cell itself can be the same (ie you don't need a text field
in some rows and popups in others, etc...) then you could just refill
the popup appropriately in an implementation of the table delegate
method:
- (void)tableView:(NSTableView *)tableView willDisplayCell:(id)
cell
forTableColumn:(NSTableColumn *)tableColumn row:(int)row;
This gives you a hook to configure the cell for the specific row. You
can use it to fill the popup with different items or to set the text
color of your text field or other things of that sort.
