NSDatePickerCell -- Ever Worked ??

As a relatively new Cocoa developer, this is my first posting to this list. So please forgive any (unintentional) faux pas.


The app I currently working on uses a NSTableView where several of the fields are date and time data. I've successfully added NSDatePickerCells to the TableColumns. The cells display the date and time data just fine, but I cannot get *editing* to work correctly. I can not select the individual time and/or date elements, and the control arrows to the right increment/decrement only the left-most element (ie. month for date in mm/dd/yyyy display or hour in hh:mm:ss ) Additional strange behavior is that the font color does not change from black to white when row is selected (and uses a dark blue background). Also, there is no indication of date/time element selection (light-blue) -- even if set 'drawsBackground' is NO (making cell background white, even when row is selected and dark blue).

The most frustrating part is that if I create a NSDataPicker control outside of a NSTableView, it works beautifully. And the documentation states that NSDataPicker relies on NSDataPickerCell for the majority of it's internal functionality.

I found an old posting (http://www.cocoabuilder.com/archive/message/cocoa/2005/5/12/135702) from Troy Stevens of the Apple Cocoa Framework group in May, 2005 saying that the NSDatePickerCell didn't work in NSTableView. I just downloaded the latest XCode 2.4 (running on 10.4.7) and it appears it's still not fixed. How disappointing!!!!

So my question is: has anyone ever successfully used a NSDatePickerCell in a NSTableView ? And if so, what were the secret incantations to get it to work ?

    TIA,
     John
