I have some buttons in my window's toolbar that are bound to an
NSArrayController (selectNext, selectPrevious, add, remove, etc).
This is a non-document based CoreData app. My AppDelegate is also the
window (with the toolbar) delegate and I implement
which works fine for the Save button because the Save button's target
is the app delegate but it doesn't get called for any of the buttons
whose target is the array controller. This leads me to think that
toolbar validation is sent to the target of the toolbaritem. Is that
correct? If so, I expect that I will need to subclass
NSArrayController and put the validation there. What would be cool is
subclassing NSArrayController, adding a delegate, and somehow
forwarding the message. Or maybe I can just forward some messages to
the NSArrayController. This is not something I've ever done but I
remember hearing people talk about message forwarding in Cocoa and
WebObjects.
Any tips are appreciated.
Thanks
Marc
