Hello,
I have some problems with OneToMany-Relationships in Entity Beans. When I try
to get entries via the corrensponding getter method, the return Collection
contains all results twice. I have initalized the Collections as HashSet, why
can this happen? Are there some common mistakes I make?
Christoph
| public class UserDataEntityBean implements Serializable {
| private long id;
| private UserEntityBean user;
| private Date lastupdate;
| private Collection<StudyEntityBean> studies;
|
| ...
|
| public UserDataEntityBean() {
| this.studies = new HashSet<StudyEntityBean>();
| }
|
| ...
|
| @OneToMany(fetch=FetchType.EAGER, cascade = {CascadeType.ALL},
mappedBy="userdata")
| public Collection<StudyEntityBean> getStudies() {
| return studies;
| }
|
| public void setStudies(Collection<StudyEntityBean> studies) {
| this.studies = studies;
| }
| }
|
The method called is "getStudies".
