Keep the state of ManagedBean in page change

Question

I have a entity Artist and this artist should have one or many Musics.

When user click in "New Artist", can fill all fields for an artist (name, address, style and etc). This form is associated a managed bean called ArtistMB. As I said, Artist can have one or many Musics, so inside this form user should click in "New Music" and be redirected to another page new_music.xhtml, but the user has not saved Artist in database yet, all content of ArtistMB should be saved in memory for now, because when user finishes adding new Music, this Music will be added to a Set<Music> inside Artist bean, and after all this the Artist bean will be saved in database.

How can I do it? If a use @ViewScoped, then the state of ArtistMB will be lost when I redirect to another page new_music.xhtml.

I would use the same window, probably by opening a modal window that allows add/update the music for the current artist reference. In that way, you can still use the `@ViewScoped` bean and there won't be need to navigate to a new view. — Luiggi Mendoza, Oct 12 '15 at 17:37
I cant use modal. I should put informations about Music in new page — Ronaldo Lanhellas, Oct 12 '15 at 17:50
Then save the artist reference somewhere like session or database, retrieve the same artist in the new page and do the modifications. — Luiggi Mendoza, Oct 12 '15 at 17:51
Easiest solution if you need new page would be `@SessionScoped` and storing there `Artist` object and after edit nulling it. — Geinmachi, Oct 12 '15 at 18:23
I read about @ ConversationScoped but this annotation don't exists in JSF 2, and i'm using Spring not CDI. I think this @ ConversationScoped is my solution beucase i can keep the state of ManagedBean while i desire. — Ronaldo Lanhellas, Oct 12 '15 at 18:29
`@ConversationScoped` belongs to CDI and it's easier to invalidate by just removing the query string parameter. — Luiggi Mendoza, Oct 12 '15 at 19:10
I dont think that use SessionScoped is a good solution. Sorry — Ronaldo Lanhellas, Oct 12 '15 at 19:18

You can put your Artist into the Flash before navigating to your musics-page, see this question.
