When using aaa.hbm.xml file and bbb.hbm.xml file,
both has attribute 'list', and their ids are as another table's id(tablename:aaa_bbb),
this is required.
than list has attribute 'index', name : serial
but the primary key indeed in database aaa_bbb is serial and aaa's id.
would you tell me my errer ?
thank you very much
