Details:
When loading its data, NSOutlineView was asking for the number of sub-items
within each item using outlineView:numberOfChildrenOfItem: -- including for
items that aren't expandable. Cocoa first inquires whether the item is
expandable using outlineView: isItemExpandable: .
To fix this, I changed the first line of NSOutlineView's method
_loadDictionaryStartingWith:atLevel:
from:
num = [_dataSource outlineView: self
numberOfChildrenOfItem: startitem];
to:
if ([_dataSource outlineView: self isItemExpandable: startitem])
num = [_dataSource outlineView: self
numberOfChildrenOfItem: startitem];
That works for my application, making it compatible with Cocoa.
