Question about Seam Hotel Booking Demo

[jebberwocky.jeffliu.potix.com]

Hello everyone

In the org.jboss.seam.example.jpa.ChangePasswordAction.java:

 public void changePassword()
   {
      if ( user.getPassword().equals(verify) )
      {
         user = em.merge(user);
         FacesMessages.instance().add("Password updated");
         changed = true;
      }
      else 
      {
         FacesMessages.instance().add("verify", "Re-enter new password");
         revertUser();
         verify=null;
      }
   }

From the above about the the entity is modified, my question is where the tx.commit() takes place?

Does Seam take care this?

Thank you

(guessing without looking for component type, flushmode etc)

The flush/commit happens automagically when the method returns

Thank you!

When I write to use AJAX component to replace the demo jsf component. And call the same method-changePassword, the
sql statement
'
Hibernate: update Customer set name...
'
won't appear in my console. It seems that the transaction is not commit.

Does anyone have an idea why? Did I miss any setup file or filter?

Or, does anyone know which class takes the commit action?

Thank you very much
