Hi all, I have as follows in Interface builder:
- A superclass with a @property NSOrderedSet *properties containing zero or more instances of objects, as well as some normal string properties. All the objects inherit from the superclass. - An NSTreeController whose content object is bound to the selection of an NSArrayController. The NSTreeController is configured with the children key path "properties" - An NSOutlineView whose content is bound to my tree controller's arrangedObjects. The outline view has two columns, each bound to a string property on arrangedObjects. When I run my app, the outline view populates and changes its contents when I change the selection of the array controller. The columns show the string properties as expected. However, no children are displayed and there is no disclosure triangle. I have verified with breakpoints that the tree controller does access my "properties" and that a set is returned with contents of the right objects. Likewise, changing the children key path to a non-existing property will yield a KVO-compliance exception. I've read through the docs and spent some time googling, but nothing I've found has suggested a reason for the children to be missing. What am I doing wrong?
