Hi,

1) How can I access the objId property in the BaseItem from Subclass1 so that it can be used by the set declaration to associate with Subclass2?

I am not basing the <set> off of "id" as the key because there is more customizations not shown here to do CUD for different versions of the same object (using the sql-X to customize the persister).

Basically, there is no foreign key constraint on parentObjId and ObjId.


2) If I wanted the property parentObjId at the BaseItem level, how should I be writing the <set>?
<property name="parentObjId" column="parent_obj_id" />


Hope to get some response on this. We are running into a wall.


Thanks!
