[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-5440) Joined collection expressions not properly "rendered" in JPA Criteria queries

Joined collection expressions not properly "rendered" in JPA Criteria queries ----------------------------------------------------------------------------- Key: HHH-5440 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5440 Project: Hibernate Core Issue Type: Bug Affects Versions: 3.5.4 Environment: hibernate-core 3.5.4, hibernate-entitymanager 3.5.4, hsqldb 2.0.0, mac os x 10.6, java 1.6.0_20 Reporter: Koen Molkenboer Assignee: Steve Ebersole Fix For: 3.6.0.Beta4, 3.5.6 Attachments: hibernate-bug.zip Time Spent: 2h 44m Remaining Estimate: 0h The situation is as follow: I have an User class which has a collection of elements which is a Set of Role enum values and I want to search for users which have one of more roles. I want to use the CriteriaBuilder, because I have a search form with a lot of fields which are optional. The User class: @Entity @Table(name = "USERS") @Access(AccessType.FIELD) public class User implements Serializable { @Id @GeneratedValue(strategy = GenerationType.AUTO) @Column(name = "ID") private Long id; @Column(name = "USERNAME", unique = true, nullable = false, length = 128) private String username; @ElementCollection @Enumerated(EnumType.STRING) @Column(name = "ROLE") @CollectionTable(name = "USER_ROLES", joinColumns = @JoinColumn(name = "USER_ID")) private Set<Role> roles = new HashSet<Role>(); ... } The enum Role: public enum Role { ROLE_1, ROLE_2, ROLE_3; } Creating the query with the CriteriaBuilder Set<Role> roles = new HashSet<Role>(); roles.add(Role.ROLE_1); roles.add(Role.ROLE_2); CriteriaBuilder criteriaBuilder = entityManager.getCriteriaBuilder(); CriteriaQuery<User> criteriaQuery = criteriaBuilder.createQuery(User.class); Root<User> root = criteriaQuery.from(User.class); criteriaQuery.where(root.join("roles").in(roles)); TypedQuery<User> query = entityManager.createQuery(criteriaQuery); query.getResultList(); This is the exception: java.lang.IllegalArgumentException: Parameter value [ROLE_2] was not matching type [java.util.Set] at org.hibernate.ejb.AbstractQueryImpl.registerParameterBinding(AbstractQueryImpl.java:360) at org.hibernate.ejb.QueryImpl.setParameter(QueryImpl.java:359) at org.hibernate.ejb.criteria.CriteriaQueryCompiler$1$1.bind(CriteriaQueryCompiler.java:194) at org.hibernate.ejb.criteria.CriteriaQueryCompiler.compile(CriteriaQueryCompiler.java:247) at org.hibernate.ejb.AbstractEntityManagerImpl.createQuery(AbstractEntityManagerImpl.java:437) ... This all works with OpenJPA 2.0.0
