Automatically expanding all the children of an NSOutlineView?

Question

I'm writing a wizard with template categories and I'm contemplating using an nsoutlineview to present the user with a hierarchical list of possible templates.

However I can't seem to find a way to automatically recursively expand all of my NSOutlineView's items. I tried

 [templatesOutline expandItem:nil expandChildren:YES];

... but that only expanded the first level of items.
