Null property exceptions

Hello,
   I can't get past NullPropertyException's when I try to save changes to my editing context.  I have an object, pool, that I add an entry to with the Entry.createEntry operation.  Then, in turn, I add an EntryScore obejct to the entry object.  Note that the entryScore relationship in Entry (the one causing the problems) is set to "propagate primary key".  I have tried making it both mandatory and optional with the same results.  Any ideas what may be causing this?

Here's the basic code:

   EOQualifier poolQual = Pool.NAME.eq(name);
   pool = Pool.fetchRequiredPool(ec, poolQual);
   entry = Entry.createEntry(ec, "DEFAULT", "pw", true, false, new Integer(0), "", false, false, false, new Integer(0), pool, user);
   EntryScore es = EntryScore.createEntryScore(ec, 0, 0, 0, 0, 0, 0);
   entry.setEntryScore(es);
   ec.saveChanges();

exception (on the SaveChanges line):
