[Hibernate-devel] Saving parent before children

[Mark W. <mor...@al...>]

Hi all...

Is there a way for Hibernate to persist the parent before any children? 
 I've an object Foo which has a child Bar, and the mapping looks like this:

<class name="Foo">
  <id name="id">
    <generator class="assigned" />
  </id>
  <one-to-one name="bar" class="Bar" />
</class>

<class name="Bar">
  <id name="id">
      <generator class="assigned" />
  </id>
</class>

I'm having problems because Bar's id must be a foreign key into Foo. 
 Because Bar gets created before Foo, I get a constraint violation.  Is 
there a way around this?  I suspect that this would also be necessary to 
support normalized mappings.

Thanks,
-Mark
