Hello,
I am having difficult mapping a child to its grandparent. The configuration is this:

Grandparent is one-to-one with Child is one-to-many with Grandchild
Grandparent has Child property
Child parent property linked to Grandparent and holds a list of Grandchild.
Grandchild has a parent property linked to Grandparent.

The table column is defined as "INVLVD_PER_SERL varchar2(32) NOT NULL"

There are two places in the application where this configuration exists. One works and the other throws a null column reference exception on insert.

Has anyone else run into this and solved it?

Thanks in advance
K
