 Post subject: XML import problem: primary key ignored, many-one ignored

Hi

I am importing an XML document, and I am having two problems.
1. Hibernate is ignoring embedded id's and generating new ones
2. Hibernate is not reading the second Object in a many-one relationship

We need to embed the id (foreign key) in order to create relationships between objects where we do not cascade on save.

Thank-you for your help

Chris Love
