Technically this can be done by mapping a foreign key column as an
ObjAttribute. Still it would go against the spirit of Cayenne. I
suggest to use a real ItemType object. DataObjectUtils.objectForPk
(..) should be a pretty efficient way to get a hold of ItemType
instance, as after the object is fetched for the first time, it will
be served from shared cache on subsequent calls.

Hi,
Given a new object I'd like to be able to set on of the properties
(a 'to'
property) without having the other object(only the ID). e.g.
Item is the object I'm creating. It has a property called ItemType
which is
another object. I have the ItemType ID but not the actual object.
I'd like
to have a method called Item.setItemTypeID(Long itemTypeId).
Is this possible?
Cheers,
Dave
