If I remove
<generator class="foreign">
<param name="property">structural</param>
</generator>
it gives an error:
The element 'id' in namespace 'urn:nhibernate-mapping-2.2' has
incomplete content. List of possible elements expected:
'urn:nhibernate-mapping-2.2:meta urn:nhibernate-mapping-2.2:column
urn:nhibernate-mapping-2.2:generator'.
How do I fix this?
Thanks,
Robert
