Leonardo Uribe commented on MYFACES-3886:
-----------------------------------------
In your case this web config para is useful:
org.apache.myfaces.NUMBER_OF_SEQUENTIAL_VIEWS_IN_SESSION
See the documentation at:
http://myfaces.apache.org/core22/myfaces-impl/webconfig.html
By default this is set to 0, but if you have more than one window/tab/dialog in
your application, you should increase the number, so the views are not
discarded.
It should work, because the algorithm was designed to keep track of upcoming
POST request and keep them in sequence. Let us know if the param works for you
to close this issue, or review it further.

> Key: MYFACES-3886
> URL: https://issues.apache.org/jira/browse/MYFACES-3886
> Project: MyFaces Core
> Issue Type: Bug
> Components: General
> Affects Versions: 2.2.2
> Environment: PrimeFaces 4.0.12.
> Reporter: Adam Balazs
>
> When I use DialogFramework (of PrimeFaces), it's adds a new view to the
> session every time. The problem is that when I post an AJAX request to the
> original view, the _keys list is not updated, only the view get updated in
> the _serializedViews map.
> After I reach the limit defined with the
> org.apache.myfaces.NUMBER_OF_VIEWS_IN_SESSION context-param, MyFaces gets the
> first element in the _keys list (which is the container view) - assuming that
> this is the oldest view in the session - and remove the corresponding view
> from the _serializedViews map by the key. But clearly it is not, as I already
> posted some AJAX requests to it.
> I think the optimal behavior would be the following: when a view gets an ajax
> request the code should remove the the key from the _keys list and than add
> it as a last element.
> The related class is
> org.apache.myfaces.application.viewstate.SerializedViewCollection at the if
> condition started at line 87.
> My question is if it is an intended behavior or if it's a bug.
