Full stack trace of any exception that occurs:
WARN [org.hibernate.jdbc.AbstractBatcher] JDBC driver did not return the expected number of row counts

Name and version of the database you are using: Oracle 10g

Seems that when i insert or update account the first idbag (roles) in the mapping will be really not persisted (but query are executed!)
if i change order (first profiles and then roles) profiles will be not persisted :(

I have noticed that the first idbag is persisted only when the second idbag is empty

I have this warn WARN [org.hibernate.jdbc.AbstractBatcher] JDBC driver did not return the expected number of row counts

Thanks who help me
