use final for BeanModel fields

[nille hammer <ta...@winfonet.eu>]

Hi Guys,

just a little side note on Filip´s suggesion. Instead of initializing the BeanModel in onActivate() you could do this:

private final BeanModel<User> model; {
  model = beanModelSource.create(User.class, false, componentResources);
  model.get("username").sortable(false);
}

Mind the final. This way the BeanModel is only created once. With onActivate() it is created every time the page is requested, which is less efficient. Of course this only works, if you do not want to change the BeanModel after creation.

Cheers nillehammer
