Finding a jsf component in a FacesContext

Finding jsf components recursively by id

 

public UIComponent findComponentRecursivelyById(String id) {

 UIComponent result = null;
 UIComponent root = FacesContext.getCurrentInstance().getViewRoot();
 if (root != null) {
  result = findComponent(root, id);
 }

 return result;

}

private UIComponent findComponent(UIComponent root, String id) {

 UIComponent result = null;
 if (root.getId().equals(id))
  return root;

 for (UIComponent child : root.getChildren()) {
  if (child.getId().equals(id)) {
   result = child;
   break;
  }

  result = findComponent(child, id);

  if (result != null)
   break;
 }

 return result;

Working with lazy associations

Persistent Object : An object with an id existing in the database that we pulled to the session. Transient Object : An object with no id that has not yet been persisted.

Lazy initialization exception Fires if there is access to the detached object after commit. For example: {    s = sessions.openSession();    Transaction tx = s.beginTransaction();    Hibernate.initialize();    User u = (User) s.createQuery("from User u where u.name=:userName").setString("userName", userName).uniqueResult();    Map permissions = u.getPermissions();    tx....
