The problem I'm having is that when the menu is used to update the cell in the table view, I just cannot get the darn thing to redraw. At all. (at least until after the menu tracking returns and it goes away). I've tried:
Remember, a table view doesn't have a unique NSCell object per table cell; instead the same cell object is used to draw every table cell in a column. So changing the cell's value yourself isn't going to affect what's shown in the table. The value stored in the cell when it's drawn in the table is the result of the dataSource's objectValueForTableColumn: method.
So it sounds like what's happening is that your fake-menu, during mouse tracking, hasn't yet updated the data model that's acting as the table's data source. If so, the table cell isn't going to change its appearance. You either have to stuff a new value into the data model during tracking, or play games with the data source's objectValueForTableColumn: method to make it return the interim value when the right row/column is requested.
