Re: Strange localInstanceOfObject behaviour...

You can't localInstanceOfObject a new object (one that has not been committed yet).  There's no snapshot yet, so it would have odd side-effects if they allowed you to do so (it would mean that when you save both editing contexts, it would commit twice, i would assume).  Not sure if old versions of EOF let you, but it's been this way for a while.

I think I am losing my mind.... 

I have a newly created object in an editing context and I am making a local instance of it in a another editing context ..... however localInstanceOfObject always returns null!! What gives?!

I make local instances of new objects in other places with no issues ..... usually 99.9% of problems are of my own doing, but this one is baffling me. Is this a bug introduced in 5.3.1 when they fixed radar 4240473?
