I’ve tested this on both 2.3 RC2 and Edge. This pastie contains  
model, helper and view: [http://pastie.org/415742](http://pastie.org/415742)

When I save a vocabulary - its terms don’t save. I’m fairly sure it  
worked in RC1. Would appreciate any insight.

I just realized that :reject\_if was causing the problem. What  
happened to it in latest rails? Could anyone explain?
