Seems to work fine and suits my needs perfectly but it makes me uneasy.

Trust in your instincts, because they don't tell lies.

Seriously smacks of EOF commandment violations to me:

<http://wiki.objectstyle.org/confluence/display/WO/EOF-Using+EOF-The+EOF+Commandments >

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.
