Hi
I've search through the archives, and found some threads about this
subject, but nothing answering my question... If I'm wrong I'd be
happy to be redirected to interesting posts.
My main question is : how to use bindings and NsComboBox correctly.
More particularly, I want the application user to be apple to add item
through the interface.
I've created a NSArrayController that is responsible for a set of
NSManagedObjects.
One of the related entity property is a 'category' relationship.
Another CategoryArrayController is associated to that entity.
What I want to do is to manage Categories through a NSComboBox. I've
set bindings to :
content : CategoryArrayController.arrangedObjects
contentValues : CategoryArrayController.arrangedObjects.category
value : TransactionArrayController.selection.category
That works fine for programmatically added category value : I can
select them through the NSComboBox. However, I cannot add a new
category through the user interface. When I enter it, I get a message
:
2005-11-28 11:44:10.198 test[426] *** -[NSCFString? _isKindOfEntity:]
selector not recognized [self = 0x3f7b90]
Does anyone have a idea for that ?
Kind regards
Julien
