[composite-id] Objects cannot be saved , no errors output.

Suppose this scenario :

class Site has one Sting key : Sitename
class User has two keys (composite key) : Sitename + Username
I wrote User.hbm.xml as follows :

Code:

<class name="foo.User" table="User">
  <composite-id>
    <key-property name="SiteEnglishName" type="java.lang.String"/>
    <key-property name="Username"        type="java.lang.String"/>
  </composite-id>
</class>

I also implemented equals() and hashCode() in class User.

By this defination , I can query User correctly.

But , when I want to add new User , it just doesn't work.
I am sure I set the two keys correctly.
When I turn set 'show_sql' to true , I found hibernate just 'SELECT' and did nothing.
There is no 'INSERT' statement found.

What's the problem ?

P.S. Hibernate 2.1 beta2

Have you done Session.flush() or a Transaction.commit() after Session.save() ?
