 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.
