Hi
I have a problem with a Entity with 3 unidirectional ManyToMany collections. The entity is:
| public class Media implements Serializable, Comparable<Media> {
| ..
|
| @javax.persistence.ManyToMany( cascade = { javax.persistence.CascadeType.PERSIST, javax.persistence.CascadeType.MERGE } )
| @javax.persistence.JoinTable(name = "nv_media_category", joinColumns = @javax.persistence.JoinColumn(name = "media_id", nullable = false), inverseJoinColumns = @javax.persistence.JoinColumn(name = "category_id", nullable = false))
| private Set<Category> categories = new HashSet<Category>();
| @javax.persistence.ManyToMany( cascade = { javax.persistence.CascadeType.PERSIST, javax.persistence.CascadeType.MERGE } )
| @javax.persistence.JoinTable(name = "nv_media_content", joinColumns = @javax.persistence.JoinColumn(name = "media_id", nullable = false), inverseJoinColumns = @javax.persistence.JoinColumn(name = "content_id", nullable = false))
| private Set<Content> contents = new HashSet<Content>();
| @javax.persistence.ManyToMany( cascade = { javax.persistence.CascadeType.PERSIST, javax.persistence.CascadeType.MERGE } )
| @javax.persistence.JoinTable(name = "nv_media_comment", joinColumns = @javax.persistence.JoinColumn(name = "media_id", nullable = false), inverseJoinColumns = @javax.persistence.JoinColumn(name = "comment_id", nullable = false))
| private Set<Comment> comments = new HashSet<Comment>();
|
| ..
|
| }
|
The problem is when create a new Media Entity and the collection comments is empty the follow code give a exception in the emanager.flush();
|
| try {
| emanager.persist(media);
| emanager.flush();
| } catch (Exception ex) {
| throw new MediaDaoException(ex);
| }
|
|
the exception:
| 11:15:21,690 ERROR [MediaServiceBase] [create]Exception: com.dnovae.nova.core.media.MediaDaoException: javax.persistence.PersistenceException: org.hibernate.PropertyValueException: not-null property references a null or transient value: com.dnovae.nova.core.comment.Comment.comment
