[eclipselink-users] Problem with loading of data with a OneToMany relati

["Christian (VuuRWerK) Seifert" <vuurwerk.christian@xxxxxxxxxxxxxx>]

Hi,

I've got a problem with my OneToMany relationship. The depending data won't be loaded. Here a shorted listing of my coding:

================= SNIP =================

public class Group {

  private String name;

  @OneToMany(mappedBy = "group", fetch = FetchType.EAGER)

  private List<Entry> entries = new ArrayList<Entry>();

  // ... getter/setter

}

public class Entry {

  @ManyToOne

  @JoinColumn(name = "FK_GROUP_ID")

  private Group group;

  // ... getter/setter

}

================= SNAP =================

I try to fetch the data using the JpaEntityManager (the jpaEm var) and ExpressionBuilder (the builder var):

================= SNIP =================

Query qry = jpaEm.createQuery(builder.get("name").equal(builder.getParameter("searchName")), Group.class);

qry.setParameter("searchName", name);

Object result = qry.getSingleResult();

================= SNAP =================

So the "result" is a valid instance of Group but the list of entries are empty, although there are 3 entries with the correct group-id in the database. There is no other errors by eclipselink or anything else.

Hope someone can help me and I'm very glad about some suggestions. Thanks in advance.

Regards

Christian
