No Problem,
Personally, I'm don't usually use named entities. They seem a little pointless
since they just get created and popped into the context variables without
initialization. For example, the user entity that gets pushed into the
authenticator bean in some examples. It is only useful once the authenticator
has authenticated the login, loaded the user and outjected an instance of the
user. I can't see much use for named entities over the factory methods except
possibly in the user case where you might want a blank instance available to
avoid any null exceptions, and you can't use a factory since the user may not
have logged in yet.
In your case, you may want to look at the @Factory annotation instead. You can
annotate access methods for the entities in your backing beans with any name
you like, it will outject the entities as a named context variable. If you do
this, you won't need to reference the entities as MyBacking.getEntity1
i.e.
|
| class MyBackingBean
|
| private Entity entity1;
| private Entity entity2;
|
| @Factory('entity1')
| public getEntity1() {
| return entity1;
| }
|
| @Factory('entity2')
| public getEntity2() {
| return entity2;
| }
|
| }
|
Now, in your jsf page, you can reference #{entity1} and #{entity2}
It all depends on how you initialize your entities, whether you pass entities
around or rely on parameters (the method I prefer).
You have to bear in mind that factory methods get called whenever you reference
#{entity1} (or 2), so if you have any weird pre-initialization that happens to
load the entities, you have to make sure that has run before you access the
factory. For this reason, I prefer to use parameters since it is less coupled.
Lastly, having the bean in conversation scope shouldn't be a problem, what's
the problem with it?
