Subject Re: problem with om classes
Date Thu, 11 Oct 2007 20:42:09 GMT
Hm, you have defined the foreign key twice:
<foreign-key foreignTable="autori" onUpdate="none" onDelete="none">
   <reference foreign="autore_id" local="autore_id"/>
   <reference foreign="autore_id" local="autore_id"/>
</foreign-key>

perhaps removing one of the references helps ?

It should not be necessary to define an interface. Can you remove the 
empty interface and see what happens ?
