Seriously smacks of EOF commandment violations to me:

See: #6, #8.

I'd use awakeFromInsertion or create a cover accessor (lazyProperties(), setLazyProperties()), and in a purely naming convention vein, try to avoid having Entities with plural names, it makes it too easy to confuse them with relationships.
Thanks David. In this case I don't want to use awakeFromInsertion as the relationship is very, very optional (i.e. small % of entities have not-null relationship.) Info in #8 definitely validates my unease and your advice. I'll go with the cover accessor.

Naming conventions... I do use singular entity names in almost every case. Properties just makes sense plural for me even though it's always a to-one relationship. It holds a properties list in a text attribute which from a dba perspective probably should be normalized as a bunch of PropertyValue entities but from an efficiency perspective works perfectly the way it is.
