Criteria Query Issue with Projection and restriction
----------------------------------------------------

                 Key: HHH-3371
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3371
             Project: Hibernate3
          Issue Type: Bug
          Components: query-criteria
    Affects Versions: 3.2.6
         Environment: Hibernate version: 3.2.6ga, MySQL 5
            Reporter: Michael Kuhinica


When I try to add a restriction to a property with a projection, hibernate generate the SQL using the property alias on the where clause instead of the property name.
Here is an code example:
      Criteria c = session.createCriteria(Customer.class).setProjection(
		Projections.projectionList()
			.add(Projections.property(Customer.PROP_ID), "id")
			.add(Projections.property(Customer.PROP_NAME), "name")
		)
		.add(Restrictions.like(Customer.PROP_EMAIL, email))
		.add(Restrictions.like(Customer.PROP_NAME, name));

And the generated SQL:
    select
        this_.ctm_id as y0_,
        this_.ctm_name as y1_ 
    from
        customers this_ 
    where
        this_.ctm_mail like ? 
        and y1_ like ?

Notice that hibernate used the right name for the customer e-mail (that has no projection on it) but it used an alias for the name that have a projection set.
