[jboss-user] [JBoss Seam] - @OneToMany not initializing

I am creating a SEAM  based application and in it I have a one to many relationship between a study and a biospecimentype.  I used the DVDStore example Category, Categories and CategoriesBean as a reference.  When I load a list of biospecimentypes using the following code:

    
  |     List<BiospecimenType>  biospecimenTypes;
  |     Map<String,BiospecimenType> biospecimenTypeMap;
  | 
  | 
  | @Create
  |     public void loadData() {
  |     	biospecimenTypes = em.createQuery("from BiospecimenType bst")
  |               .setHint("org.hibernate.cacheable", true)
  |               .getResultList();
  | 
  |         Map<String,BiospecimenType> results = new TreeMap<String,BiospecimenType>();
  |         
  |         for (BiospecimenType biospecimenType: biospecimenTypes) {
  |             results.put(biospecimenType.getName(),biospecimenType);
  |         }
  |         
  |         biospecimenTypeMap = results;
  |     }
  | 
  | 

and then try to access the list via:



  |                         <h:selectManyListbox 
  | 							value="#{search.biospecimenTypesSelected}" 
  | 							size="10" 
  | 							converter="#{biospecimentypesbean.converter}">
  |                             	<f:selectItems value="#{biospecimentypesbean.biospecimenTypes}" />
  |                         </h:selectManyListbox>
  | 				<BR/><BR/><h:commandButton action="#{search.testSelected}"
  | 				                           value="TestSelection"/>
  | 				<BR/><BR/><h:outputText value="Selected Categories: "/><h:outputText value="#{search.selItemsOutput}"/>						
  | 

I get the following error in my JBoss server log but if I comment out the @OneToMany property in the BiospecimenType bean the list is built:

The definintion for the relationship in the BiospecimenType bean is:

  | 	@OneToMany(mappedBy="biospecimenType")
  | 	private Set<Study> studyCollection;
  | 
The definition for the relationship in the Study bean is:

  | 	@ManyToOne
  | 	@JoinColumn(name="BIOSPECIMEN_TYPE_ID")
  | 	private BiospecimenType biospecimenType;
  | 

Shouldn't this relationship be initialized when the biospecimentype query is run?   The foreign key necessary exists and is not null for these relatiionships.  I am new to SEAM and EJB3.0 so please bear with me.  I am using the DALI plug-in for Eclipse to generate the entity beans and relationships.

Thanks
Jerry
