hql insert doesn't work when inserting into a table with composite-id
----------------------------------------------------------------------

          Key: HHH-3434
          URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3434
        Project: Hibernate3
      Issue Type: Bug
      Components: query-hql
  Affects Versions: 3.2.6
     Environment: 3.2.6GA, any database
       Reporter: Ning Zhang


I have a table serving as an association table, so the Id of the table is just the ids from the linked tables. The mapping file looks like:

  <class name="UserPt" table="user_pt" >
    <composite-id>
       <key-property name="userId" type="java.lang.Long" column="user_id"/>
       <key-property name="ptId" type="java.lang.Long" column="pt_id"/>
    </composite-id>
  </class>

And I need to run some HQL to insert the association into the table like:

INSERT INTO UserPt(userId, ptId) SELECT user.id, pt.id FROM...........

When I run this HQL, it gives an error saying:

"can only generate ids as part of bulk insert with either sequence or post-insert style generators".

I logged the bug in http://opensource.atlassian.com/projects/hibernate/browse/HHH-3400, but it is closed because I asked for a workaround. So this time I am not asking for anthing, just report the bug.
