Dora Rajappan commented on MYFACES-3804:
----------------------------------------
I have opened a jira issue 3817 for state saving problem with ajax redirect.
Once that is fixed the view key fix automatically applies to redirect scenario.
Shall I commit this code. This address when there is no key initially in
client window mode and an ajax request is made.
> Use the same key in server side state saving for ajax requests
> --------------------------------------------------------------

> The current code for server side state saving creates one key per request to
> store the view state. This is ok, but it is not necessary for ajax requests.
> The reason why is not necessary is because you can never go back to a page
> when using ajax. If you are on page A and the current request is an ajax
> request and it returns to the same page and the view is the same that the one
> that has been restored, the key or the token sent does not need to change,
> what changes is the internal state of the view. From the client side the page
> is the same. We can take advantage of this fact and just update the state
> stored in SerializedViewCollection for the view.
> The challenge here is detect when this strategy is applicable. For example,
> what happen if there is an ajax redirect? It looks is a good idea for
> implement in 2.2, because it avoids to store unnecessary information into
> session and optimize the use of each view slot.
