Re: NullPointer on EOAdapter.fetchedValueForValue

You werw right it was my eomodel. One of our many-to-many join tables 
wasn't set up properly. Thanks.

Re: NullPointer on EOAdapter.fetchedValueForValue






Couple wild guesses:

Something's wrong with your eomodel, one of the attributes isn't 
properly set up.

You're using change notification or some other method of inserting 
snapshots into the database context, and the snapshot includes 
attribute keys that aren't in the eomodel, or vice-versa. (This can 
happen when you have multiple instances with change notification and 
one has an out-of-date eomodel.)
