Hi all, I have a collection of entities I'd like to display in an NSOutlineView with an NSTreeController. My issue is, I don't know how to set the bindings. All examples I've seen are where the Tree Controller contains ALL entities of a type. I need just a set of them, but nothing I've tried to set in my bindings comes out in the outline view. It doesn't result in an error, it just doesn't show anything.
My objects are chained like: Alpha (multiple) -> Beta (one) -> Delta (multiple) (delta has references to itself via parent and children relationships) I can select the Alpha and see all the beta's Deltas in a plain Array Controller and NSTableView, so those bindings are fine, but I cannot see anything in the NSTreeController connected to NSOutlineView. The managed object context is set fine. The other NSTreeController bindings are set up as: - Entity: Delta, Prepares Content - Fetch predicate: "parent == nil" - Children: "children" I've tried to set up the "Content set" to a variety of settings and none of them work. I'm setting up the Outline View bindings as expected to the Tree Controller's values, just like the Table View's bindings and like I've seen in tutorials but maybe I'm off there too. Any suggestions or better tutorials??
