9:18 a.m.
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
