Binding to NSTreeController

Subject: Binding to NSTreeController

Hey there everyone,

I have managed to get an NSBrowser binding to an NSTreeController which contains an XML Document. Everything is formatted properly in the NSBrowser and works well, however...

I also have an NSTextField on the Window that I would like to bind to an attribute of the object that is currently selected in the NSBrowser. Now I did what I would do if this was an NSArrayController and bound the value of the NSTextField to "selection.displayName". I know that the displayName part of this key path is correct because it is what is being used to render the NSBrowser.

But when I run the code the NSTextField always shows "No Selection" no matter what I click on in the NSBrowser.

Any Ideas?

Chris
