eager loading leads to unwanted recursion

Hi,

I've used the composition pattern to define a virtual file system:

Code:

@Entity
public class VirtualFolder extends VirtualFile {
 
  @Composition
  @OneToMany(mappedBy="folder", cascade = CascadeType.ALL, fetch=FetchType.EAGER)
  private Set<VirtualFile> contents = new HashSet<VirtualFile>();

if I now load the root folder with

Code:

session.createCriteria(VirtualRootFolder.class).uniqueResult();

I get the whole tree of all sub folders and sub sub sub folders.. but I only want one level, not all. If I remove the fetch annotation and define the fetch strategie in the criteria, I get the result I wanted:

Code:

    session.createCriteria(VirtualRootFolder.class).setFetchMode("contents", FetchMode.JOIN).uniqueResult();

Is there a way to define the same behaviour by annotations?

Best regards
Sebastian Baltes
