2:21 p.m.
I am creating a Help Ticketing system and I am following the SEAM documenation and making
use of the EntityHome for CRUDing my Ticket Entity. The initial creation and updating
works great, however when I go to view tickets, then click on a ticket which gets
redirected back to my original ticket.xhtml page, with ticketId as a parameter, I can not
for the life of me get the ticket to display.
I need another pair of eyes to see where I am going wrong.

when I click on the Ticket Number I get in the url bar:
http://localhost:8080/fiapps/ticket.seam?ticketId=1&dataModelSelectio...
so I know the ticketId is getting passed. But the ticket is not getting loaded. Here are
some additional classes.
TicketHome.java
| @Name("ticketHome")
| public class TicketHome extends EntityHome<Ticket> {
|
|
| @Factory("ticket")
| public Ticket initPerson() {
| return getInstance();
| }
|
| protected Ticket createInstance() {
| Ticket ticket = new Ticket();
| return ticket;
| }
|
| public String getCreatedMessage() { return "New Ticket (#{ticket.subject})
created"; }
| public String getUpdatedMessage() { return "Ticket (#{ticket.subject})
updated"; }
| public String getDeletedMessage() { return "Ticket (#{ticket.subject})
deleted"; }
| }
|
ViewTicketsBean.java - the relevant part
| @Name("viewTickets")
| @Stateful
| @Scope(ScopeType.CONVERSATION)
| public class ViewTicketsBean implements ViewTickets {
|
| @In(create=false, value="tempTicket") @Out(value="tempTicket")
| private Ticket tempTicket;
|
| @Logger
| private Log log;
|
| @DataModel
| private List<Ticket> tickets;
|
| @DataModelSelection
| private Ticket ticket;
|
| @In(create=true)
| private EntityManager entityManager;
|
| ...
|
Any help would be greatly appreciated.
