Multiple Joins using criteria
-----------------------------

                 Key: HHH-4893
                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-4893
             Project: Hibernate Core
          Issue Type: Bug
          Components: query-criteria
    Affects Versions: 3.3.2
            Reporter: praveer gupta


I need to do multiple joins between two tables using Hibernate criteria.

I tried doing the following:

Crtieria criteria = session.createCriteria(Cat.class, "cat");

criteria.createAlias("cat.kittens", "first", CriteriaSpecification.LEFT_JOIN)
.add( Restrictions.eq("first.name", "Foo"));

criteria.createAlias("cat.kittens", "second", CriteriaSpecification.LEFT_JOIN)
.add( Restrictions.eq("second.name", "Bar"));

criteria.list();

I get the following: org.hibernate.QueryException: duplicate association path

I tried looking for issues regarding the same and found http://opensource.atlassian.com/projects/hibernate/browse/HB-555. 

I am not aware whether we can do multiple joins using criteria now.
