Hello,
I have an NSOutlineView with a DataSource, and some of the items have
an initial status of opened while others have an initial status of
closed.
How can I make NSOutlineView respect that status?
By default, the outline view will display every item collapsed, but I
did not found a proper way to make it expand the items that are saved
as expanded in the data source.

Pablo, you need to implement some more optional datasource methods. I think you need to read this:
