Unable to JOIN embedded objects in Criteria API
-----------------------------------------------
Key: HHH-5792
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5792
Project: Hibernate Core
Issue Type: Bug
Components: entity-manager, query-criteria
Affects Versions: 3.6.0
Reporter: scLee
Priority: Blocker
Attachments: Client.java, CriteriaApiTest.java, Name.java
Exception is thrown when trying to JOIN embedded attribute in Criteria API. E.g. having the following entity:
{quote}
@Entity
public class Client implements Serializable {
@Id
public int id;
@Embedded
public Name name;
}
@Embeddable
public class Name implements Serializable {
@Column
public String firstName;
@Column
public String lastName;
}
{quote}
The following code
{quote}
CriteriaQuery< Client > cq = cb.createQuery( Client.class );
Root< Client > root = cq.from( Client.class );
cq.where( cb.equal( root.*join*( "name" ).get( "firstName" ), "foo" ) );
{quote}
throws this exception:
{quote}
