However in this example they access the array directly, and they seem to add objects to the table with [array addObject:object], which works when the application is compiled. When i attempted this, the table wouldn't refresh correctly and i had to implement insertObject: at<key>AtIndex and removeObjectFrom<Key>AtIndex methods.

The example only uses addObject: during initialisers etc.

Now my table will refresh and items are added, but I get an error:
*** Illegal NSTableView data source (<MyController: 0x3391a0>). Must implement numberOfRowsInTableView: and tableView:objectValueForTableColumn:row:


Have you set the data source outlet for the table view?

I don't get it. I can't figure out why in the Apple sample listed above they can just access the array directly, while my table won't refresh if I do it.

See above, and "Programmatic modifications to arrays not noticed by table view" at:
<http://homepage.mac.com/mmalc/CocoaExamples/controllers.html>


I used bindings in the same way. And if I have to implement numberOfRows... and objectValyeForTable... methods, why use bindings anyway???

You don't have to implement them.
