[Mono-osx] [MonoMac] NSMutableDictionary FromObjectsAndKeys problem

[kjpou1]

Hello all


I am working with a mutable dictionary with bindings to an ArrayController
and am having problems creating a NSMutableDictionary using the
FromObjectsAndKeys.

It works for a NSDictionary but not when creating a NSMutableDictionary.

The example code below shows what I am talking about.

	var objects = new NSObject[3] {new NSString("AAAAA"),
						new NSString("BBBBB"),
						new NSString("CCCCCC")};

	var keys = new NSObject[3] {new NSString("firstkey"),
						new NSString("secondkey"),
						new NSString("thirdkey")};
			
	var dict2 = NSDictionary.FromObjectsAndKeys(objects,keys);
			
	//var dict = NSMutableDictionary.FromObjectsAndKeys(objects, keys);
	var dict = NSMutableDictionary.FromDictionary(dict2);
			
	myContentArray.AddObject(dict);

The implementation between NSDictionary.cs and NSMutableDictionary.cs are
different for that method and not sure why.

Any help would be appreciated

Kenneth

----------------------------------
If you uncomment the //var dict =
NSMutableDictionary.FromObjectsAndKeys(objects, keys); it gives the
following error:
