NSArrayController: Modify contents programmatically

Hi all,

I want to change the contents of an array that is managed by an NSArrayController via bindings. Does the Controller recognize insertions and removals on the array properly, even if they are done directly on the array bypassing the NSArrayController (without using NSArrayController>>addObject) ?

I use a similar setup in an application. The NSArrayController is used to fill a NSTableView. The content array is changed from the outside. The newly inserted element only shows up, when the TableView is resorted by clicking the column header. This is strange, since if I register an observer for the array using the addObserver:forKeyPath:options:context:-selector, I get the right change results in observeValueForKeyPath:ofObject:change:context:. The NSArrayController should get these changes too, doesn't it?


Thanks in advance

felix
