[jboss-user] [JBoss Seam] - Re: how can I do optimistic locking with crud framework?
I'm probably doing this completely wrong... I took contactHome out of components.xml
and replaced it with this class:
| @Name("contactHome")
| @Scope(ScopeType.CONVERSATION)
| public class ContactHome extends EntityHome<Contact> {
|
| @Logger
| private Log log;
|
| public ContactHome() {
| super();
| setCreatedMessage("New contact #{contact.firstName} #{contact.lastName}
created");
| setDeletedMessage("Contact #{contact.firstName} #{contact.lastName}
deleted");
| setUpdatedMessage("Contact #{contact.firstName} #{contact.lastName}
updated");
|
| }
|
| @Begin
| public String beginEdit() {
| log.info("Conversation begun by beginEdit()");
| return null;
| }
|
| @End
| public String update() {
| log.info("Conversation ended by update()");
| return super.update();
| }
|
| @Factory("contact")
| public Contact initContact() {
| return getInstance();
| }
| }
|
|
And I edited pages.xml to add the beginEdit action:
| <page view-id="/editContact.xhtml"
action="#{contactHome.beginEdit}">
| <param name="contactId" value="#{contactHome.id}"
converterId="javax.faces.Long"/>
| </page>
|
Everything works the way it did before (including "last edit wins") though now I
get a traceback on the console after update:
| 14:22:42,553 ERROR [PhaseListenerManager] Exception in PhaseListener
RENDER_RESPONSE(6) afterPhase
