I don't think the schema you posted actually does what you want.  When
you create an IItem object, the form will embed a form to create a new
IUnit object (which will embed a form to create a new IItem and so
on).  Even apart from the infinite recursion in the form, I don't
think you are intending to create a new IUnit every time you create an

I think you are intending to initialize a -reference- to an existing
IUnit when you create the IItem and vice-versa.  In X3.0, you use a
vocabulary to do this.  See if the available documentation and
examples for those meets your needs.


How great is the love the Father has lavished on us,
