OpenJPA persists children before parent!

[Patrick Shea <pa...@ps1.net>]

I have a very simple parent/child entity setup with a onetomany from the parent and manytoone on the child.

I create the parent, create the child, add the child to the parent collection and persist the parent.

At that point OpenJPA is trying to insert the child before the parent which results in a parent not found fk violation.

I'm I missing something or to I have to manually persist the parent first then add the children?

OpenJPA can order the SQL statements to satisfy the foreign key constraints.
However, you must tell OpenJPA about the existing foreign keys; otherwise,
by default, it does neither read physical foreign key information from the
database, nor creates foreign key constrainst while defining schema for new
tables.

The information on how to tell OpenJPA about foreign keys is available in
