As this is on 10.6.2, I’ve filed rdar://problem/7456424, referencing Rob’s report.

Considering the other issues I’m having with it, I suspect I’m headed down the same path. For the record, this will be three for three times I’ve tried to use NSTreeController in one of our apps and have been unable to do so.
Thank you, Greg and Rob, for your input. Maybe a fix for this can make 10.6.3, with any luck.
Best,
