I'm using an NSDictionaryController object to control the data
provided to an NSTableView object. I'm attempting to use key-value
coding through the dictionary controller to manipulate the data in a
bindings-compatible way, by calling the method -arrangedObjects on
the NSDictionaryController, and then manipulating the
NSDictionaryControllerKeyValuePairs that this method returns in an
array.
Any luck?
I am having a similar problem - mutable dictionary objects that are
themselves stored in a dictionary will be presented as immutable
dictionaries by the NSDictionaryController. This makes it impossible
to bind controls to keypaths that drill into dictionaries below the
level of the outermost container.
i.e. even if arrangedObjects.value should point to a mutable
dictionary, attempts to edit arrangedObjects.value.someKey via a UI
control will generate the following error:
*** -[NSCFDictionary setObject:forKey:]: mutating method sent to
immutable object
Having a workaround for this would be really nice - has anyone found
one? I will file a bug as I don't think this is the behavior most
would expect.
This is turning something that would have "just worked" in about
fifteen minutes into yet another quest for a messy workaround...
Thanks in advance,
Rick
