Hello,
Could anyone answer for my questons.
For what we use "nested conversations", when we use it?
(any examples welcome)
For what is @LoggedIn, is this a king of filter that we check acces for that "logged" user? Has this any connection with JAAS?
For what and how we user "RedirectFilter"
thanks for help

- Nested conversations or good for e.g. multiple "sub-conversations" within a conversation. The main conversation could be a complex product search, and the sub-conversations could be product orders. Or imagine that you edit an entity in a conversation, and during that you edit multiple sub-entities in nested conversations. There are complex web apps where nested conversations are helpful. Keep in mind: conversations hold and isolate states and they can co-exist with other conversations.

- LoggedIn checks if there is a logged in user. Have a look at the LoggedInInterceptor class of the booking example. btw: What is JAAS?

- RedirectFilters are important for keeping the state of a conversation or other scope even after a page redirect. In classic JSF all redirects lead to the loss of non-session/application scoped data.
