DetachedCriteria doesn't create alias on subcriteria
----------------------------------------------------

         Key: HHH-1685
         URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-1685
     Project: Hibernate3
        Type: Bug

  Components: query-criteria  
    Versions: 3.1.3    
    Reporter: John


DetachedCriteria has two createCriteria methods:

	public DetachedCriteria createCriteria(String associationPath)	throws HibernateException 
	public DetachedCriteria createCriteria(String associationPath, String alias) throws HibernateException

However, the code for both was identical - they called the inner criteria's createCriteria(String) method. The version with the alias did not call the inner's version with the alias.  The following patch snipped shows the change:

 	public DetachedCriteria createCriteria(String associationPath, String alias)
 	throws HibernateException {
-		return new DetachedCriteria( impl, criteria.createCriteria(associationPath) );
+		return new DetachedCriteria( impl, criteria.createCriteria(associationPath, alias) );
 	}


This bug was discovered while trying to link a 2-deep subquery to its parent via aliases.  (Surfacing this issue might only be possible with the patch HHH-952 in place - I'm not sure.  Seems like a bug regardless, as it definitely fixed my alias reference issue.)  I'll get an example posted shortly.
