This works fine as long as you do not have any child objects that need to be created. What if actionContact is null? Then all child objects are also null.

Retrieving business objects is a business process which I think should be kept separate from the tag libs. Having said that, I typically do something like the following: public class UpdateContactAction implements Action, ModelDriven { private Contact contact = new Contact() ; private ContactManager contactManager; public UpdateContactAction(ContactManager contactManager) { this.contactManager = contactManager; } public Object getModel() { return this.contact ; } public void execute() { this.contactManager.update(contact); } } ContactManager would be implemented as: public class DefaultContactManager implements ContactManager { private PersistenceManager persistenceManager; public DefaultContactManager(PersistenceManager persistenceManager) { this.persistenceManager = persistenceManager ; } public void update(Contact contact) { Contact actualContact = (Contact)persistenceManager.load( Contact.class, contact.getContactId()); // copy mutable fields // save actualContact } ... } M > > For example: > > You have a create customer screen in which you select a parent company > (which is a object list from the action).
