In cocoa its very tempting to write a single line of code like:

It does work. I have defined a core data entity that conforms to
IKBrowerItem protocol and my IKImageBrowserView is working with
bindings. I think you still need to point the delegate and data source
outlets to an object that implements the datasource methods:

All good ideas from Andy. I sometimes get arround this issue by using
