Hello All,

In reading through the docs and forum, I have seen reference to the composite-element mapping as an alternate way to define a parent/child relationship. However, I cannot find documentation on how to use it. Would someone please point me in the right direction.

For the curious, here is what I would like to accomplish:

I have a parent/child (one-to-many defining) relationship between two classes. The child is a lifecycle class and so has no existence beyond its parent. In the database, the child table's PK is comprised of a ChildID (synthetic integer) and an FK to the ParentID (also a synthetic integer).

From what I have read, I need a mapping like this in my Parent:

However, <id> is not a valid child of <composite-element> so I do not know how to map that column.

Any help would be appreciated.

Thank you for your time,
Jay
