--------------------------------------
Hi Leonardo,
I've already set this context param to 2.
These are a related context params i have set:
<context-param>
<param-name>org.apache.myfaces.NUMBER_OF_VIEWS_IN_SESSION</param-name>
<param-value>10</param-value>
</context-param>
<context-param>
<param-name>org.apache.myfaces.NUMBER_OF_SEQUENTIAL_VIEWS_IN_SESSION</param-name>
<param-value>2</param-value>
</context-param>
<context-param>
<param-name>org.apache.myfaces.FLASH_SCOPE_DISABLED</param-name>
<param-value>false</param-value>
</context-param>
<context-param>
<param-name>org.apache.myfaces.USE_FLASH_SCOPE_PURGE_VIEWS_IN_SESSION</param-name>
<param-value>true</param-value>
</context-param>
My original issue(not this) has been solved by setting the numbder sequential
views to 2 (this way the dialog framework won't discard my original view). But
if I open this dialog frequently (which will generete a new view every time),
the mentioned issue still exists.

> 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.
