I have upgraded to JSF 1.2 in anticipation of Seam 2.0, but I am having a problem with restoring the view after timeout. This occurs when using a4j:commandLink.

I get the exception below and a yes/no popup appears with the text

| View state couldn't be restored - reload page ?

By adding the following to page.xml, I can catch the error, but the popup still appears.

 <exception class="java.lang.IllegalArgumentException">
|      <redirect view-id="/error.xhtml">
|         <message severity="warn">Problem restoring view. Please try again.</message>
|      </redirect>
|   </exception>

How can I catch this error and redirect without having the popup appear?

I am using JBoss 4.2.1, Seam 1.2.1, and JSF 1.2 that comes with JBoss 4.2.1.
