[jboss-user] [JBoss Seam] - Re: Finding an entity using a non- at Id unique identifier

[uke]

Thanks for your response!

I tried overriding the find()-method with the following:

  | @Override
  | public Employee find() {
  |     EntityQuery eQuery = (EntityQuery)Component.getInstance("employeeIdByEmploymentNumber");
  |     Long l = null;
  |     if(eQuery.getResultCount() > 0)
  |         l = (Long)eQuery.getSingleResult();
  |     
  |     getEntityManager().joinTransaction();
  |     Employee result = getEntityManager().find( getEntityClass(), (l == null ? getId() : l));
  |     if (result==null) result = handleNotFound();
  |     return result;
  | }
  | 

I then aimed the commandButton towards /viewEmployee.xhtml, and added  to the -tag for it, but it gives me LazyInitializationException and TransientObjectException.

I wasn't really sure on what to do with the overridden find method, since I'm not really sure why my session is closed, and why it works when I reload the page.

Thanks
uke
