Hi Bruce
No, I don't think so. If you look at Castor's example, they have:
<!-- Product has reference to ProductGroup,
many products may reference same group -->
<field name="group" type="myapp.ProductGroup">
<sql name="group_id" />
<xml name="group" node="element" />
</field>
and ProductGroup has id as the identity.
I looked through my code and found one difference. In Castor's example these
steps occur in one transaction:
(1) lookup ProductGroup
(2) assign ProductGroup to Product
(3) create Product
In my code, (1) is done in a separate transaction than (2) and (3). Is this
a problem? Can someone verify this?
Regards
Keith C
