Conversation injection is null
Hi all,
I have a ViewScoped bean where I want to inject de conversation in. In the logging I see that the conversation id is null. I use JBoss 6 but I also tested this with jboss 7. Does anybody have any ideas?
@Stateful
@ConversationScoped
@Named
public class CategoryManager {
/**
*
*/
private static final long serialVersionUID = 9179727796959552384L;
private static final Logger log = Logger.getLogger(CategoryManager.class);
@PersistenceContext(type= PersistenceContextType.EXTENDED)
private EntityManager entityManager;
private Long categoryId;
@Inject
private Conversation conversation;
@Produces
@Named
public List<Category> getRootCategories() {
log.debug("entered getRootCategories");
if(!conversation.isTransient()) {
conversation.begin();
log.debug("not transient - conversation id: " + conversation.getId());
System.out.println("not transient - conversation id: " + conversation.getId());
}
log.debug("conversation id: " + conversation.getId());
System.out.println("conversation id: " + conversation.getId());
if(getCategoryId() == null) {
log.debug("categoryId == null");
CriteriaBuilder builder = entityManager.getCriteriaBuilder();
CriteriaQuery<Category> cquery = builder.createQuery(Category.class);
Root<Category> category = cquery.from(Category.class);
cquery.select(category).where(builder.isNull(category.get("previousCategory")));
List<Category> rootCategories = entityManager.createQuery(cquery).getResultList();
return rootCategories;
}else{
log.debug("categoryId != null so return category with selected Id and underlying categoryList");
CriteriaBuilder builder = entityManager.getCriteriaBuilder();
CriteriaQuery<Category> cquery = builder.createQuery(Category.class);
Root<Category> category = cquery.from(Category.class);
cquery.select(category).where(builder.equal(category.get(Category_.id), categoryId));
List<Category> rootCategories = entityManager.createQuery(cquery).getResultList();
return rootCategories;
}
}
@Produces
@Named("category")
public Category getCategory() {
log.debug("entered getCategory");
if(categoryId != null) {
log.info("categoryId: " + categoryId);
Category cat = entityManager.find(Category.class, categoryId);
log.info("size of categories of the selected category: " + cat.getCategories().size());
return cat;
}else{
log.info("categoryId == null");
log.info("create new category");
return new Category();
}
}
@Produces
@Named
@nl.ami.marketplace.market.Category
public Long getCategoryId() {
log.debug("getCategoryId: " + categoryId);
return categoryId;
}
public void setCategoryId(Long categoryId) {
this.categoryId = categoryId;
}
}
