Query on a one-to-one association with foreign generator does not work
----------------------------------------------------------------------

         Key: HHH-1849
         URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-1849
     Project: Hibernate3
        Type: Bug

  Components: core  
    Versions: 3.2.0.cr2    
 Environment: There is no exception under hsqldb but there is one with msde or firebird.
    Reporter: Sebastien Cesbron
 Attachments: test-foreign.zip

I have 2 classes Master and Slave with Master that has a foreign generator on slave.
  <class name="Master">
    <id name="oid">
      <generator class="foreign">
      <param name="property">slave</param>
      </generator>
    </id>
    <property name="libelle" type="string" />
    <one-to-one name="slave" class="Slave" constrained="true"/>
  </class>
If I do :
query = session.createQuery("from Master master where master.slave=:slave");
query.setParameter("slave", slave);
query.list();
There is a problem because the parameter is not set. Under hsqldb, there is no exception but the query return nothing. Under msde or firebird there is an exception. Under firebird it is "org.firebirdsql.jdbc.FBMissingParameterException: Not all parameters were set.".

The same query on slave's oid works :
query = session.createQuery("from Master master where master.slave.oid=:oid");
query.setParameter("oid", 1);
query.list();

I've attached a simple project that shows the problem. I have tested this project with hibernate 3.0.5 and hibernate 3.2.0cr2. It works with the first one but not with the latter one.
