Factory with @Out in Weld

[umajeric]

Hej,
I would like to implement such kind of behaviour in weld:

@Out(scope=SESSION)
private List<Objects> myList;

@Factory("myList")
public void initMyList() {
  myList = ...;
}

my solution looks like this:

@Produces 
@Named("myList")
public List<Object> initMyList() {
  return someNewList();
}

My problem now is: when I call some method on bean which contains those methods and in it I call initMyList(); my list on page is not populated.

Any idea?

thans for help.

Show the full code of the beans

I found out that my problem was not in the code but in icefaces. I had some other issue.
This solution with the @Producer annotation is it correct, or is there some other one?

Yes, a producer method (or even field) is the new @Out (sort of)

[umajeric]

And how would this solution look like on field?

[nickarls]

@Produces @Named @SessionScoped
private List<Object> myList;

[umajeric]

yes, but where to write then a factory method, that actually initialises the list?

[umajeric]

Hi,
I found out the solution. it would look like this:

@SessionScoped
public class MyListProducer {
@Produces @Named
private List<Object> myList;

@Inject
public void init() {
myList = new ArrayList();
}
}

thanks.

Whilst this will work, I would not recommend it. The reason we have both producer methods and fields is to allow you to do initialization work in a method if needed...

why not recommended? this is exactly what I need.

Generally it's perhaps more readable to have the entire operation encapsulated inside a producer method instead of having the reader look around for the initialization part.
