Thanks to everyone for their suggestions, the examples shown on
http://homepage.mac.com/mmalc/CocoaExamples/controllers.html
were invaluable and have solved the problem.
Thanks
Vince

Hi there
I have an NSArrayController that is bound to the columns in an
NSTableView. The table view correctly picks up the values that are in
the array managed by the controller when it initially displays, but
does not update when I add new objects to the array. All other
functionality seems fine. Are there any known issues with using an
NSArrayController with an NSTableView. Visual inspection of the array
managed by the NSArrayController shows that the added values are in
fact there, attempting to force the table view to reload it's data by
means of reloadData also has no effect. Does anyone have any
suggestions ?
Thanks in advance
Vincent
You can find some useful information on mmalc's excellent bindings
website:
http://homepage.mac.com/mmalc/CocoaExamples/controllers.html
Look for the section titled "Programmatic modifications to arrays not
noticed by table view". Basically, calling [array
addObjects:someObjects] will not cause the array controller to be
notified of the change to array. The technique I use is to call:
[[self mutableArrayValueForKey:@"array"] addObjects:someObjects]
Good luck,
Jeff Gilbert
