what's different between AjaxStateManager and JspStateManage

[bengan]

in my web APP I use myfaces1.2.4 and richfaces3.2.2 . I config :

<context-param>
 <param-name>
 org.apache.myfaces.NUMBER_OF_VIEWS_IN_SESSION
 </param-name>
 <param-value>5</param-value>
</context-param>

and I config :

<state-manager>
 org.apache.myfaces.application.jsp.JspStateManagerImpl
</state-manager>

but when I visited some pages more then 5 my APP throws Exception:
javax.faces.application.ViewExpiredException - myxxx.jsf No saved view state could be found for the view identifier: myxxx.jsf

but when I try to config <state-manager> use AjaxStateManager, no any Exception be throwed.

why?? what's different between AjaxStateManager and JspStateManagerImpl??

Hello,

AjaxStateManager is a special class that aim is to support state saving in AJAX requests (as by its name).

I've created an issue to support MyFaces configuration parameters: https://jira.jboss.org/jira/browse/RF-5079. As for now you can use com.sun.faces.numberOfViewsInSession and com.sun.faces.numberOfLogicalViews

that meet if I config <state-manager> as JspStateManagerImpl it can not support state saving in AJAX requests ??
