Here's one newbie trap to avoid

EOUtilities.objectWithFetchSpecificationAndBindings throws EOObjectNotAvailableException - if there is no matching object, so far so good.

You do a fetch with no results and get an EOObjectNotAvailableException. But watch out for. . .

EOUtilities.objectsWithFetchSpecificationAndBindings it throws EOObjectNotAvailableException, but only if it can't find the fetch specification.

If you are used to the way object (singular) WithFetchSpecAndBindings behaves you are out of luck with this one. You do a fetch with no results and get no exception. You may have been expecting an EOObjectNotAvailableException, but you are never going to get it. Why didn't someone come up with an EONoFetchSpec exception instead? What does objectWithFetchSpecificationAndBindings throw if it can't find the fetch spec? Anything?

It's so subtle it is almost evil. Just glad I didn't waste too much time with it. One more newbie trap to avoid, but at least it is in the documentation.
