Strange behavior using view-based NSOutline (Sourcelist)

Question

I have a (new in Lion) view-based NSOutlineView as Sidebar SourceList in my app using CoreData + NSTreeController + Bindings + NSOutlineView and an Object as NSOutlineViewDelega

Answer 1

I was wondering how you achieved the source list that's visible on the screenshot.

I have created a little sample project, which does the same and includes the feedback from @anton-ivanov:

• Display a list of items
• Edit the items in a master-detail fashion
• Remove and add items
• Usage of bindings

Check out besi/mac-quickies on github. Most of the stuff is either done in IB or can be found in the AppDelegate
