nsarraycontroller

I have a NSArrayController bound to a NSTableView. With this I have the typical Add/Remove buttons.

While Adding an item is very straight forward (I call a method, create an object with default values and add it) I have problems deleting objects from the controller. I know I can do this the easy way when connecting the button with the remove action from the ArrayController. But this is not what I want. I need to remove the object manually because I have some additional code to process.

Anway, removing objects seems far more complcated then I expected. It already tried:

NSArray *items =  [doToItemsArrayController selectedObjects];
[doToItemsArrayController removeSelectedObjects:items];

or

NSIndexSet *iSet = [doToItemsArrayController selectionIndexes];
[doToItemsArrayController removeSelectionIndexes:iSet];

None of them seems to work. How do I remove the selected Object from an NSArrayController with Objective-C code?
