NSOutlineView Bug

Here's another NSOutlineView Bug.

When the user option-clicks on the disclosure triangle, the result is the item is expanded and all of it's children are expanded.

The problem is that....

- (BOOL)outlineView:(NSOutlineView*)view shouldExpandItem:(id)item;

only gets called once for the first item, even though many items are being expanded. Actually I need a routine like...

- (BOOL)outlineView:(NSOutlineView*)view shouldExpandAllItems:(id)item;

If I've got an item with 10000s of sub items, I want to block this action so the app doesn't just hang trying to display thousands of items (like the content of a hard disk for example)
